ODM BLDC Motor — Custom Design Manufactured To Your Requirements.
Your application requirements, our design and manufacturing — for engineering-led customers building a new product around a custom motor. Shenghe's in-house R&D team takes the customer's machine envelope, duty cycle, voltage source and target torque/speed curve and designs the motor electrical and mechanical from scratch — magnet selection, winding spec, frame dimensions, shaft geometry, controller pairing — using FEA simulation to predict torque/speed/efficiency before any metal is cut. Prototype on the in-house dynamometer; revision loops in 2–3 weeks; tooling cut once design is frozen; first-article inspection on the first 5–10 production units. Direct factory in Cixi, Ningbo with over a decade of focused BLDC manufacturing, ISO 9001 / CE / RoHS production, English-first export desk speaking engineer-to-engineer language (FEA outputs, dyno reports, FAI sign-off, IP arrangement, NDA, tooling investment split), customer holds the design IP, no grey-market resale.
NDA on first inquiry — bilateral, before any engineering review
Customer holds the design IP — no grey-market resale, no sales to your competitors
FEA simulation + dyno-tested prototype — predicted vs measured curves shipped with first article
Prototype in 4–6 weeks after design freeze; revision loops 2–3 weeks
Your Requirements, Our Design + Manufacturing
For Engineering-Led Customers Who Know What Their Machine Needs.
ODM is the engagement model engineering-led customers use when their machine specifies the motor — target torque curve, voltage envelope, mounting interface, IP rating, certification — but no off-shelf SKU fits. The customer brings the application requirements; Shenghe brings the motor design and the production line. In-house R&D team with motor design specialists running CAD, motor simulation software for torque/speed/efficiency prediction, FEA on the magnetic circuit. In-house dynamometer test bench for prototype validation; IP rating chamber; endurance test rigs. The factory speaks engineer-to-engineer fluently — FEA simulation outputs, dyno test reports, FAI documentation, tooling investment split, IP arrangement, bilateral NDA — none of which are afterthoughts.
Customer brings application requirements; Shenghe designs the motor electrical and mechanical from scratch
FEA-simulated concept before tooling commitment — predicted vs measured curves shipped with the first prototype
Bilateral NDA on first inquiry — design files, FEA outputs and dyno reports retained on access-controlled servers
Customer owns the design IP; Shenghe owns the manufacturing know-how — locked in writing in the ODM contract
OEM vs Custom vs ODM
Pick The Engagement Model That Matches Your Project.
Three distinct engagement models for brand and engineering customers — they sit on a continuum from "your brand on our standard SKU" through "modifications to a standard SKU" to "designed from scratch from your application requirements". Picking the right one upfront is the difference between a 4-week first order and a 16-week first order — ODM is for the cases where there's no standard SKU close enough to modify.

Brand customers with an existing motor design needing branded production
Customers needing minor spec changes (shaft, mounting, voltage tap, encoder mount)
Engineering-led customers with no motor design — robotics, AGV, medical, aerospace
Have an existing motor design and need branded production? See OEM BLDC Motor — Private Label and Branded Manufacturing →. Need a small tweak to a standard SKU rather than a full design? See Custom BLDC Motor →. If you're not sure which fits, send the brief to the inline RFQ and engineering will recommend the model that matches your timeline and volume.
6-Step ODM Workflow
From Requirements Capture To Mass-Production-Ready Motor.
The standard ODM project path Shenghe runs with engineering-led customers. Each step has a defined deliverable, response window and gate before the next step starts — so the customer's engineering, procurement, QA and project-management teams know exactly what to expect at every stage of the 12–20 week run.
Step 1 — Requirements capture and engineering review (1–2 weeks). Customer sends the requirements pack: machine envelope drawing showing available motor space, duty cycle (continuous / S2 / S3 / peak), voltage source (battery nominal Ah or DC bus from customer drive), target rated and peak torque, target speed, ambient temperature range, IP rating environment, mounting interface (foot / flange / face), encoder requirement (resolution, signal type), controller preference (Shenghe controller or customer's drive), target lead time and volume. NDA on first inquiry — bilateral, signed before any engineering review. Engineering team reviews in 1–2 weeks and either accepts the brief, flags conflicts for relaxation (e.g., target torque incompatible with target frame at target voltage), or proposes a different envelope before formal quote.
Step 2 — Concept design with FEA-predicted curves (2–3 weeks). Engineering returns 1–2 concept variants. Each includes 3D model of motor housing and rotor, predicted torque/speed curve and efficiency map from FEA simulation, magnet grade and winding spec, frame dimensions and shaft geometry, controller pairing recommendation, tooling investment estimate, MOQ for first run, target lead time. Customer reviews variants over WhatsApp / Teams / Zoom screen-share with engineering walk-through and picks the variant that fits the application best. Tooling investment split (customer-funded / shared / Shenghe-funded against volume commitment) is locked at this stage and written into the ODM contract.
Step 3 — Prototype build and dyno test (4–6 weeks). First prototype manufactured. Where possible, prototype runs on existing housing tooling so the customer holds a real motor before tooling investment is committed. Bench test on the in-house dynamometer: rated torque, peak torque, no-load speed, current at rated and peak load, temperature rise across duty cycle, dielectric strength, Hall sequence verification. Dyno test report shipped with the prototype — measured values vs predicted values from the concept stage, so the customer sees how close the build matched simulation before committing to tooling.
Step 4 — Customer integration and validation (timeline customer-driven). Customer integrates the prototype into their machine and runs the actual duty cycle. Standard validation 2–6 weeks; medical device or aerospace customers running formal qualification protocols (IEC 60601, RTCA DO-160, MIL-STD) take longer. Engineering revisions handled in 2–3 week loops — send the test data, engineering returns a revision spec (winding tweak, magnet grade change, mounting adjustment, IP improvement, encoder change), revised prototype shipped. Most ODM projects close after 1–2 revision loops; engineering-heavy projects 3–4 loops before design freeze.
Step 5 — Tooling cut and first-article inspection (3–4 weeks). Once design is frozen and customer signs off in writing, tooling is cut: housing mould, shaft fixturing, custom connector over-mould, any custom mechanical parts. First-article inspection (FAI) on the first 5–10 production units against the frozen design pack — dimensional check, electrical test, IP rating verification, full performance curve on the dyno, label and packaging proof. FAI report shipped to customer for written sign-off before the rest of the production batch runs.
Step 6 — Mass production with QA at each station. Mass production runs through the standard production line slot. CNC machining, stator winding, motor assembly, controller PCB and end-of-line testing — every motor receives an individual end-of-line test record (no-load current, no-load speed, Hall sequence, resistance per phase, dielectric strength, plus rated-load test for ODM customers requiring per-unit traceability). Pre-shipment AQL inspection on site or via live video — third-party SGS / BV / Intertek / TUV welcome. Documentation pack per shipment: test report per unit if specified, lot traceability records, material certificates, ISO 9001 / CE / RoHS DoC on customer letterhead. Branded packaging and freight from Ningbo per OEM rules — see /oem-bldc-motor/ for the branded-shipment workflow.
Engineering Capability
The R&D Team, Tools And Test Equipment Behind The Design.
The reason Shenghe ODM projects close in 12–20 weeks rather than 6+ months is that the design, simulation, prototype build and dyno qualification all happen on the same site — engineering walks from CAD station to winding line to dyno bench in five minutes. No subcontracted simulation house, no third-party prototyping shop, no external test lab booking lead time on the critical path.
In-House R&D Team
Motor design specialists covering electromagnetic design (magnetic circuit, flux density, cogging torque), mechanical design (housing, shaft, bearing, sealing), winding design (turn count, slot fill, wire gauge, parallel paths) and controller pairing (six-step or FOC firmware match). Same-site as the production line, so design intent and manufacturability stay aligned from day one.
Design Tools
3D CAD for housing, shaft, end-cap and bearing geometry. Motor simulation software for torque/speed/efficiency prediction across the duty cycle. Finite-element analysis on the magnetic circuit (flux saturation, cogging torque optimisation, demagnetisation margin at peak load and high temperature). Thermal simulation for continuous-duty rating and IP-rated enclosure cooling.
Dynamometer Test Bench
In-house dyno measures torque/speed curve, peak vs rated torque, efficiency map, no-load current, temperature rise across the duty cycle. Every prototype runs through the dyno before shipment to customer — measured vs predicted curves shipped with the first article so the customer sees how the build matched simulation before tooling commitment.
IP Rating Chamber
Water-spray and dust-ingress chamber for IP54, IP65 and IP67 enclosure verification. Salt-spray cabinet for marine and outdoor application qualification. IP rating verified on prototype and on first-article inspection units — not just at design level. Specific lab certifications available on request; we don't claim accreditations we don't hold.
Endurance Test Rigs
Endurance rigs for thermal-cycling, mechanical-shock and vibration test on prototype and FAI units — load profile programmed against the customer's actual duty cycle. Lifetime estimate from the endurance test feeds into the ODM design review and the customer's reliability dossier (MTBF, B10 life). EMC pre-compliance bench for emissions and immunity scoping ahead of formal certification at an accredited lab.
Project Scope We Take
BLDC and BLDC servo motors 50W to 10kW direct-drive and geared (planetary, worm, helical, spur), matched controllers. Out-of-scope: AC induction motors, brushed DC motors, <10W (too small for our winding line), >50kW (frame size beyond our existing machine envelope), stepper motors. Engineering will flag scope mismatches at requirements stage before quoting.
Every dimension that's "off the shelf" on a stock SKU is a free design variable on an ODM project. Engineering picks the values that match the customer's application — not what's most convenient for our existing tooling.
Parameter
Standard SKU constraint
ODM design freedom
Voltage
12V / 24V / 36V / 48V / 72V / 110V / 220V common bus
Any voltage from 12V to 220V matched to customer's battery system or DC bus
Frame size
Stock frames at standard diameters and lengths
Custom diameter, custom length to fit the customer's machine envelope drawing
Shaft diameter and length
Standard tolerance bands and stocked geometry
Custom diameter, length, keyway, flat, splined or D-shaft to match customer's coupling
Torque curve
Stock rated and peak torque per SKU
Designed against customer's duty cycle — rated, peak, S2/S3 intermittent rating, stall torque
Speed envelope
Stock no-load and rated speed per SKU
Designed against customer's target speed and field-weakening range
Mounting interface
Standard foot, flange or face mount with stock bolt patterns
Custom flange dimensions, custom bolt pattern, custom face-mount, hollow-shaft mount
IP rating
IP54 standard on most SKUs; IP65 on selected models
IP54 / IP65 / IP67 with sealing matched to customer's environment (washdown, marine, outdoor, dust)
Encoder integration
Hall sensors standard; quadrature encoder optional on selected SKUs
Hall, incremental encoder (any line count and signal type), absolute encoder, resolver, or no encoder for sensorless drive
Connector
Standard JST / Molex / AMP / MIL-spec from common families
Any connector family and pinout matched to customer's harness
Controller pairing
BLD22010 / BLD6010 / BLDB6010 stock controllers
Stock Shenghe controller, customised firmware on stock controller, or design-to-pair with customer's existing drive
If your application sits inside one or two of these design freedoms only — for example just a custom shaft length on an otherwise-stock SKU — see Custom BLDC Motor →. ODM is the right model when three or more parameters need to move outside the standard SKU envelope.
Customer Profile
Engineering-Led Customers Shenghe Already Speaks To Fluently.
Generic descriptors of the engineering-led customer profiles Shenghe runs ODM projects with. Reference customer list available under NDA on request — no anonymous claims, no invented logos.
Robotics Startups
Robotics builders needing custom joint actuators with specific torque density, encoder resolution and controller pairing. Typical brief: low-cogging-torque BLDC servo for 6-axis robot arm, 24V or 48V bus, hollow-shaft for cable routing, absolute encoder for repeatability, FOC drive. Engineering-heavy revision loops on torque ripple and thermal performance are expected and budgeted into the timeline.
Specialised AGV Builders
AGV system builders needing traction and steer motors matched to the vehicle envelope, battery system and load profile. Typical brief: 48V or 72V BLDC traction motor with planetary or worm gearbox, mechanical brake, IP54 or IP65 sealing for warehouse or outdoor duty, encoder for navigation feedback, matched controller firmware for the AGV's path-planning controller. See BLDC Motor for AGV → for the application page.
Medical Device Companies
Medical device companies needing low-noise BLDC drive matched to device-specific duty cycle and IP rating. Typical brief: infusion pump, hospital bed, dental chair, lab centrifuge or surgical-tool drive — low audible noise (<45 dBA at 1m), low EMI for IEC 60601-1-2 compliance, lot traceability per shipment, and per-unit test record for the device manufacturer's regulatory dossier (FDA 21 CFR Part 820, EU MDR).
Industrial OEMs Developing New Product Lines
Industrial OEMs replacing AC induction motors with BLDC where the existing motor catalog doesn't fit — packaging machines, conveyors, sortation systems, food-processing lines, irrigation pumps. Typical brief: drop-in replacement matching existing AC motor mounting and gearbox interface but delivering BLDC efficiency, controllability and energy-monitoring inside the OEM's existing PLC or fieldbus integration.
Aerospace and Defense Subsystem Suppliers
Aerospace and defense subsystem suppliers needing custom drive motors with non-standard voltage, connector or qualification path. Typical brief: 28V DC bus per MIL-STD-704 or RTCA DO-160 voltage envelope, MIL-spec connector, vibration / shock / temperature qualification, derated to operate in the customer's environmental envelope. ITAR / EAR scope confirmed at requirements stage; export controls handled on the customer side.
E-Mobility Brands With Application-Specific Spec
E-mobility brands (e-bike, e-scooter, e-rickshaw, light EV) where the existing product line needs a motor sized to a specific torque/speed/efficiency target — for a new vehicle platform or a regulatory market segment (L1e-A / L3e in Europe, FMVSS in NA, AIS-129 in India). Typical brief: 48V to 72V hub or mid-drive BLDC, custom torque curve for the vehicle's gear ratio, IP65 or IP67 sealing, controller firmware matched to the brand's display protocol.
Profiles above are descriptive — Shenghe does not name customers without written consent. Reference customer list available under NDA on request.
IP Arrangement & ODM Contract
Who Owns What — Locked In Writing Before Any Tooling Is Cut.
Six concrete commitments engineering-led customers ask about before sending the first requirements pack. None of them are aspirational — they're the operating procedure the export desk, engineering team and contract drafting work to.
Customer Owns The Design IP
Standard ODM contract: customer owns the motor design IP — mechanical drawings, electrical spec, BOM, firmware parameters specific to the customer's application. Shenghe does not claim ownership of, license to a third party, or reuse the customer's design IP for our own products or for other customers. Patents arising from the project filed in the customer's name; trademark and brand rights belong fully to the customer.
Manufacturing Know-How Stays With Shenghe
Shenghe owns the manufacturing know-how — winding tooling, assembly fixturing, controller firmware (where the firmware is Shenghe's stock IP), QA test stand, process documentation. The two don't overlap, and the contract spells out which is which so neither side overreaches. Process improvements developed during the ODM project belong to Shenghe; design improvements specific to the customer's motor belong to the customer.
NDA On First Inquiry — Bilateral
Bilateral NDA supported on first inquiry — your standard mutual NDA template or Shenghe's one-page mutual NDA. Signed before any requirements pack, FEA output, dyno report or engineering correspondence is shared. Customer requirements files retained on access-controlled internal servers; engineering review participants under role-based access only; nothing shared with other customers; nothing used for Shenghe marketing without written permission.
Tooling Ownership
Tooling cut for the project is owned by the customer if the customer covers the tooling investment in full; jointly owned if the investment is shared; owned by Shenghe if Shenghe absorbs the cost against a volume commitment. Locked in writing in the ODM contract before tooling is cut. End-of-life: customer-owned tooling can be transferred or scrapped on customer's instruction; jointly-owned tooling per contract terms.
No Grey-Market Resale
Shenghe does not sell ODM-designed motors under our own brand, to the customer's competitors, or through B2B marketplaces — even after the engagement ends. ODM-designed inventory leaves the factory only against the customer's PO. The exclusivity is structural, not aspirational: the design is the customer's IP, so we couldn't sell it elsewhere even if we wanted to.
Brand Treatment Per OEM Rules
Once the ODM design is frozen and tooling is cut, branding (logo on housing, customer-branded carton, datasheet on customer letterhead, drop-ship under customer brand on FOB / CIF / DAP / DDP) follows the OEM workflow — see /oem-bldc-motor/. Most ODM customers run branded production from day one; some choose generic packaging on early shipments and switch to branded once volume stabilises.
Production Capability
One Site, From CAD Station To Container Loading.
The production line that runs ODM mass production is the same line that runs stock SKUs and OEM-branded production — same QA standards, same ISO 9001 documentation, same end-of-line test rig. The ODM-specific layer sits in front (engineering, simulation, prototyping, dyno qualification, FAI) but the mass-production stations are common across all engagement models.
1. CNC Machining
YT40 and Xinchuan XC36 CNC lathe lines turn motor housings, shafts and end caps to drawing tolerance. Operator-supervised, with first-article inspection on every batch. ODM custom shaft geometry, custom flange dimensions and custom housing length are programmed at this station — the prototype shaft and the production shaft come off the same lathe with the same program.
2. Stator Winding
In-house stator winding line runs the ODM-designed winding spec — turn count, slot fill, wire gauge, parallel paths — verified against the BOM at each batch start. ODM-specific parameters are locked at this station: voltage envelope, torque/speed curve, thermal class. Same SKU under ODM does not vary electrically across batches.
3. Motor Assembly
Final assembly stations integrate stator, rotor, bearings, end caps, encoder mount, sealing per IP target and Hall harness. ODM-specific fixtures (custom flange jig, custom shaft press, custom encoder alignment) added here against the frozen design pack. End-of-line cosmetic inspection feeds straight into the test bench.
4. Controller PCB
BLD22010, BLD6010 and BLDB6010 servo controller PCBs built on the same site. For ODM motor + controller pairs, controller firmware is parameterised against the ODM motor's electrical spec at the start of mass production — current limit, commutation timing, FOC tuning, protection thresholds — and locked against the BOM the customer signed off. No firmware drift between prototype and production.
5. End-of-Line Test & Dyno Bench
Performance test bench measures torque curve, no-load current, peak efficiency and thermal rise — the same dyno that ran the ODM prototype qualification runs spot checks on production batches. Every motor receives an individual end-of-line test record. Per-unit rated-load test available on ODM customers requiring full traceability.
+ Branded Packaging + Pre-Ship
Customer-artwork carton printing, foam tray and inner-pack assembly, pallet wrapping per Incoterm and destination. Pre-shipment inspection station for buyer-side or third-party audit (SGS / BV / Intertek / TUV). Documentation pack: per-unit test report (if specified), lot traceability, material certificates, ISO 9001 / CE / RoHS DoC on customer letterhead. Container loading ~2,500 motor units per 20GP, ~5,500 per 40HQ.

ODM BLDC Motor FAQ
What Engineering-Led Customers Ask Before The First Requirements Pack.
The eight questions engineering-led customers ask most often before starting an ODM project. For project-specific questions not covered here, send the requirements brief — engineering replies inside one working day on standard scope inquiries and inside 5 working days on full ODM feasibility, NDA on request.
What's the difference between ODM and OEM?
OEM = customer brings an existing motor design and Shenghe manufactures under the customer's brand (4–6 week first order). ODM = customer brings application requirements only (envelope, duty, voltage, torque target) and Shenghe designs the motor electrical and mechanical from scratch (12–20 week first order). ODM is for engineering-led customers who don't have a motor design but know what their machine needs.
What information do you need to start an ODM design?
Machine envelope drawing, duty cycle (continuous / S2 / S3 / peak), voltage source, target rated and peak torque, target speed, ambient temperature and IP environment, mounting orientation (foot / flange / face), encoder spec, controller preference, target lead time and volume. NDA supported on first inquiry — bilateral, signed before any engineering review.
How long does an ODM project typically take?
12–20 weeks from spec freeze to mass-production-ready: 1–2w requirements + 2–3w concept + 4–6w prototype + customer validation (customer-driven) + 3–4w tooling and FAI + mass-production slot. Compressed timelines possible if the design is close to an existing Shenghe SKU and tooling is reusable — confirm at requirements stage.
What's the MOQ for the first ODM production run?
500–1,000 units first run, sized to amortise design and tooling investment. Tooling investment shared customer / Shenghe based on volume commitment, locked in writing before tooling is cut. Repeat orders against locked tooling: 100–300 units. Below 500 units, see /custom-bldc-motor/ (mods to a standard SKU) instead.
Who owns the design IP — customer or Shenghe?
Standard ODM contract: customer owns the motor design IP (drawings, BOM, electrical spec). Shenghe owns the manufacturing know-how (winding tooling, assembly fixturing, QA test stand). Locked in writing. Patents from the project filed in customer's name. No grey-market resale of ODM-designed motors. Tooling owned by customer if customer-funded; jointly owned if shared.
Can you do ODM for low volume — under 500 units?
Below 500 units, ODM economics get hard — engineering and tooling cost per unit too high. Better engagement is usually Custom BLDC Motor (mods to a standard SKU like custom shaft, mounting, voltage tap, encoder mount) — uses existing tooling where possible. If your application genuinely needs clean-sheet design at low volume, send the requirements anyway and engineering will quote what's possible.
Do you have engineers who speak English / German / Spanish?
English-first export desk on requirements capture, NDA, ODM contract, prototype review and PO. Chinese for buyers and forwarders inside China. German and Spanish handled on request via the export desk for EU and Latin America customers. Engineering review meetings on FEA outputs and dyno reports run in English with screen-share on WhatsApp / Teams / Zoom.
What kind of motor projects do you decline?
ODM scope is BLDC and BLDC servo 50W–10kW, geared variants, matched controllers. Out-of-scope: AC induction motors, brushed DC, <10W, >50kW, stepper motors. Also: requirements with irreconcilable conflicts (target torque incompatible with target frame at target voltage) — engineering will flag the conflict and either help the customer relax one constraint or recommend a different approach.
