Where is the Shenghe BLDC motor factory located?

199 Xinhua Road, Xiaolin Town, Cixi, Ningbo, Zhejiang, China — postal code 315331. Cixi is a coastal city in Ningbo prefecture, on the south bank of Hangzhou Bay. The factory sits in the local industrial park 20 minutes from the Ningbo-Zhoushan port (the world's #1 cargo throughput port for the past 13 years), 1 hour by car from Ningbo Lishe International Airport (NGB) and 3 hours by car from Shanghai Pudong International Airport (PVG). Hangzhou Xiaoshan (HGH) is 1.5 hours away as a third option. The location keeps inland-haul friction off container schedules and makes the factory practical for both EU/Middle East buyers flying into PVG and India/Southeast Asia buyers flying into NGB.

What if I cannot travel — can you do a live video factory tour?

Yes — live video walk-throughs are the standard alternative for overseas buyers who cannot travel. Schedule via WhatsApp +86 18268661068 or WeChat (ID on request). The export desk hosts the call with English-speaking sales and engineering on the Shenghe side; the camera operator walks the workshop in sequence (exterior gate → CNC → winding → assembly → PCB → dyno bench → finished-motor warehouse → packaging) and stops at any station the buyer wants to inspect in detail. Random unit teardown for buyer-side inspection is supported on the call — pick a finished motor off the production line, the assembly engineer disassembles it on the bench while the camera shows winding, magnet, bearing and shaft details. Typical call runs 30–45 minutes; recordings can be shared with the buyer's QA team afterwards on request. Available 08:30–17:30 China time on weekdays; outside-hours sessions available with 3 working days notice.

What equipment is on the factory floor?

Core equipment list: YT40 CNC lathes and Xinchuan XC36 CNC lathes (multiple units, motor housing and shaft turning); in-house stator winding line with operator-supervised winding fixtures across the standard frame range (42mm / 57mm / 60mm / 80mm / 90mm / 110mm / 130mm); rotor magnet-bonding stations with curing ovens; motor final assembly stations with torque-controlled tooling and barcode-tracked work-in-progress; controller PCB SMT line for BLD22010 (DC 18–60V, 10A continuous), BLD6010 (DC 80–220V, 30A continuous) and BLDB6010 (servo controller with FOC + encoder feedback) production; dynamometer test bench measuring torque/speed curve, no-load current, peak efficiency and thermal rise; endurance test rig for 100% load duty-cycle qualification; performance test bench with oscilloscope, power analyzer and dielectric tester; component warehouse with shelved parts ready for picking; pre-shipment inspection and packaging stations. Full equipment list available on request as PDF — sent on inquiry, with model numbers, capacity per unit and calibration cycle for each piece of measurement equipment.

How big is the workshop and how many people work there?

50-person direct manufacturer covering engineering, CNC machining, winding, assembly, controller PCB SMT, QA / test bench, warehouse and English-first export desk. Workshop area covers the production line, sub-assembly stations, controller PCB SMT room, test benches, warehouse and packaging — sized for the 1,000–3,000 units per month per motor frame production capacity. Workshop has natural light through factory windows, mechanical ventilation, and standard industrial flooring; no clean-room is needed for BLDC motor production at this scale. Specific square-meter figure available on the factory tour or in the capability brochure PDF — included with the equipment list. Office area is on the same site, second floor of the production building, with engineering and export desk on the same floor as production so engineering can walk to the line in 5 minutes for OEM revisions or QA discussions.

What is the monthly production capacity?

Sustained production capacity per motor frame: 57BL frame (50W–250W) ~2,000–3,000 units/month, 80BL frame (200W–500W) ~1,500–2,500 units/month, 90BL frame (500W–1000W) ~1,500–2,500 units/month, 110BL frame (1000W–1500W) ~1,000–2,000 units/month, 130BL frame (1500W–3000W) ~500–1,500 units/month. Controller PCBs (BLD22010 / BLD6010 / BLDB6010) ~3,000–5,000 units/month. Capacity scales on advance booking — large orders (5,000+ units per SKU per month) are scheduled into the production calendar with batched shipments every 2–3 weeks rather than first-come-first-served, so production-line slot allocation stays predictable. CNY (Chinese New Year) closure 1.5–2 weeks each January or February — calendar published at the start of each Q4. See /bldc-motor-wholesale/ for the volume tier pricing structure and stocked-SKU lead-time SLA.

What quality control stations are on the line?

Six QA stations from incoming-material to pre-shipment: (1) Incoming materials inspection — copper wire grade and diameter, magnet grade verification, bearing source check, gear-blank steel certificate review against ISO 9001 supplier qualification list. (2) In-process gauge check at CNC station — first-article inspection on every batch, dimensional check against drawing tolerance. (3) Stator winding QA — turns count, slot fill, Hall sensor placement validated against BOM at each batch start. (4) End-of-line dynamometer test on every motor — no-load current, no-load speed, Hall sequence, resistance per phase, dielectric strength, temperature rise. (5) Endurance bench for 100% load duty-cycle qualification on sample basis from each batch. (6) Pre-shipment AQL inspection (in-house QA AQL 1.0) plus optional third-party (SGS / BV / Intertek / TUV) at buyer's cost. Per-unit end-of-line test record is shipped with the unit; lot-level QA records retained on file under ISO 9001 procedures.

Do you welcome third-party factory audits?

Yes — third-party factory audits, social compliance audits and quality audits are welcomed and accommodated. Common audit firms that have inspected the factory include SGS, Bureau Veritas (BV), Intertek and TUV; specific firm coverage available on request. Audit topics commonly requested by procurement teams: ISO 9001 quality management system audit, social compliance (BSCI / SA8000 framework), environmental compliance, factory production capacity verification, sample QA verification, raw-material traceability audit. Schedule with 2–3 weeks notice via the export desk so the QA team can prepare the document set the auditor will review (ISO certificates, supplier qualification list, calibration records, batch traveler samples, complaint-handling records). Audit cost is on the buyer side; Shenghe provides the access and the document set, no audit-blocking, no surprise fees.

Visit Or Verify — On Site Or On Camera

The Workshop You'd See If You Came In Person.

Most "factory" pages on supplier directories are stock images and a square-meter number. This page exists for the procurement teams who want to verify before committing — visit the workshop in Cixi or run a live video walk-through, see the named equipment on the floor, watch a random unit be torn down at the assembly station, talk to the engineering team that runs the line. The factory has been open to buyer visits and third-party audits for over a decade; the same access applies whether you're flying in for a half-day visit, running a SGS audit, or joining a 30-minute video call from Hamburg or Bengaluru.

Six Production Stations In Sequence

What The Workshop Walk-Through Covers.

The workshop walk-through follows the production sequence — same path the work-in-progress motor takes from incoming materials to packed carton. In-person visits and live video tours both cover all six stations; deeper questions (welcome) extend the call.

Row of YT40 CNC lathes for BLDC motor housing machining

1. CNC Machining

YT40 and Xinchuan XC36 CNC lathe lines (multiple units) turn motor housings, shafts and end caps to drawing tolerance. Operator-supervised; first-article inspection on every batch with calibrated micrometers and bore gauges. Custom shaft length / keyway / flange dimensions for OEM and Custom orders programmed at this station — same lathe, same program, prototype to production.

Trays of machined stator housings ready for stator winding

2. Stator Winding

In-house stator winding line covering the standard 42mm / 57mm / 60mm / 80mm / 90mm / 110mm / 130mm frame range. Copper wire diameter, turns count, slot fill and parallel paths verified against the BOM at each batch start. Hall sensor placement validated before potting. Custom voltage tap (e.g., 48V → 36V on same frame) applied at this station for Custom and ODM orders.

BLDC motor final assembly line with workers at stations

3. Motor Final Assembly

Final assembly stations integrate stator, rotor, bearings, end caps, encoder mount, sealing per IP target, and Hall harness. Each station has its own torque-controlled tooling; barcode-tracked work-in-progress so each motor's lot number ties back to the production batch. Random unit teardown for visiting buyers happens at this station — assembly engineer disassembles a finished motor on the bench while the camera shows winding, magnet, bearing and shaft details.

In-house BLDC motor controller PCBs in production rack

4. Controller PCB SMT

BLD22010 (DC 18–60V, 10A continuous), BLD6010 (DC 80–220V, 30A continuous) and BLDB6010 (servo controller with FOC + encoder feedback) PCBs built on the same site. Layout-sensitive parts (gate drivers, current-sense shunts) placed and reflow-soldered in-house, then load-bench tested with the matched motor before being paired into the customer's order. Firmware loaded and parameterised against the matched motor's electrical spec.

Dynamometer test bench with oscilloscope and power analyzer

5. Dynamometer + Endurance Test Bench

Performance dyno measures torque/speed curve, no-load current, peak efficiency and thermal rise. Endurance rig runs 100% load duty cycle for sample qualification on each batch. EMC pre-compliance bench for emissions and immunity scoping ahead of formal certification at an accredited lab. Every motor receives an individual end-of-line test record (no-load current, no-load speed, Hall sequence, resistance per phase, dielectric strength) before packing.

Finished BLDC motors palletised and ready for container loading

6. Packaging + Warehouse + Pre-Shipment

Component warehouse with shelved parts ready for picking — keeps OEM lead time short by avoiding raw-material wait. Carton labelling and pallet wrapping per Incoterm and destination requirement. Pre-shipment AQL inspection station for buyer-side or third-party audit (SGS / BV / Intertek / TUV); container loading photo on the WhatsApp group before sealing. 20 minutes to Ningbo-Zhoushan port from the factory gate.

Six Quality Control Stations

From Incoming Materials To Pre-Shipment AQL.

Procurement audit teams ask about QA before they ask about price. The six stations below cover the QA chain from raw-material receipt to container loading. Per-unit end-of-line dyno test record ships with every motor; lot-level QA records retained on file under ISO 9001 procedures and available on third-party audit.

Station	What's checked	Frequency	Records on file
1. Incoming Materials Inspection	Copper wire grade and diameter, magnet grade, bearing source, gear-blank steel certificate, lubricant batch — against ISO 9001 supplier qualification list	Every incoming lot	Material certificates and supplier batch records
2. CNC In-Process FAI	Dimensional check on housing, shaft, end cap against drawing tolerance — calibrated micrometers, bore gauges, height gauges	First-article inspection on every batch	FAI sheet per batch tied to lot number
3. Stator Winding QA	Turns count, slot fill, wire gauge, parallel paths, Hall sensor placement — verified against BOM at batch start	Every batch start	Winding traveler with measured values
4. End-Of-Line Dyno Test	No-load current, no-load speed, Hall sequence, resistance per phase, dielectric strength, temperature rise — per unit, every unit	100% — every motor	Per-unit test record sticker on motor + lot record
5. Endurance Sample Bench	100% load duty cycle for sample qualification — torque, speed, current, temperature rise across continuous-duty profile	Sample basis from each batch	Endurance test report per batch sample
6. Pre-Shipment AQL	AQL 1.0 sample plan — random unit selection, dimensional + electrical + cosmetic check against PI; optional third-party (SGS / BV / Intertek / TUV)	Every shipment	AQL inspection report; third-party report if buyer pays

Calibration records for the dyno bench, gauge equipment and test instruments are kept under ISO 9001 procedures and refreshed annually — available for review on factory audit. Non-conformance handling follows the standard 8D framework: failed unit returned with the test record sticker triggers root-cause analysis inside 7 working days, replacement from stock for standard SKUs, written 8D report for systemic batch issues.

Step 5 — Follow-up documentation and quote response. Within 1 working day after the visit: PDF capability brochure, requested ISO 9001 / CE / RoHS certificate copies, equipment list with model numbers and calibration records, samples list and pricing for any SKUs discussed, OEM / ODM feasibility note for custom projects, third-party audit document set if an audit is being prepared. Visit photos and video recording (live tour) shared on request — useful for the buyer's QA team to review post-visit.

Live Video Walk-Through For Overseas Buyers

30–45 Minute Workshop Tour, On Camera, In English.

For procurement teams who cannot travel — most overseas buyers run a live video tour before the first PO and a second tour at audit time. The format is the same as the in-person walk-through, just with the camera replacing the buyer in the room.

Format

WhatsApp / WeChat / Microsoft Teams / Zoom — buyer's choice. English-speaking sales host plus engineering on the Shenghe side. Camera operator walks the workshop in the production sequence (exterior gate → CNC → winding → assembly → PCB → dyno bench → warehouse → packaging) and stops at any station the buyer wants to inspect in detail. Standard call 30–45 minutes; longer technical-deep-dive calls accommodated.

What's Shown

Real workshop, real equipment, real workers — same workshop the in-person visitors see. Random unit teardown at the assembly station: pick a finished motor off the line, the assembly engineer disassembles it on the bench while the camera shows winding, magnet, bearing and shaft details. Equipment label and serial visible on request — useful when the buyer's audit team is matching specific units to certificate copies.

When

08:30–17:30 China Standard Time (UTC+8) on weekdays — that's roughly 06:00–15:00 in Berlin / Frankfurt, 04:00–13:00 in London, midnight to 09:00 in New York, and 06:00–15:00 in Mumbai. Outside-hours sessions (early evening for North America, late evening for Europe) available with 3 working days notice — host on call rotates depending on day.

Recording

Recording available on request — useful for the buyer's QA team to review post-call, or for sharing with stakeholders (engineering, procurement leadership, third-party auditor) who couldn't join live. Recording shared via WeTransfer / Google Drive / SharePoint within 1 working day after the call. Recording does not include any other customer's project — the workshop walk-through is generic except where a buyer-specific product is being discussed.

Audit Calls

Audit-style live calls (covering ISO 9001 procedures, supplier qualification list, calibration records, batch traveler samples, complaint-handling records) supported with 5 working days notice so the QA team can prepare the document set. Camera coverage is wider than the standard workshop tour — includes office area where ISO 9001 records are stored and the meeting room where document review takes place. Document copies shared via WeTransfer concurrent with the call.

Languages

English-first on the host side. Chinese (Mandarin) for buyers and forwarders inside China. German and Spanish handled on request via the export desk for EU and Latin America customers — typically with the German / Spanish-speaking salesperson translating between the buyer and the workshop host. Video tour content is the same regardless of language; technical Q&A may run slightly longer with translation.

Schedule a live video walk-through via the form below or directly on WhatsApp +86 18268661068 — typical setup time is 3 working days from request to call.

Visit Logistics

Airports, Hotels, Visa Letter, Pickup.

The travel-side detail buyers usually need to confirm before booking flights. The export desk handles all of it from the visit-confirmation step onwards.

Airports

Ningbo Lishe (NGB) — 1 hour by car, the closest airport. Direct flights from major China cities and selected international hubs. Best for buyers from Korea, Japan, Southeast Asia.
Shanghai Pudong (PVG) — 3 hours by car, the international gateway. Direct flights from EU, North America, Middle East, Australia, India. Best for long-haul buyers.
Hangzhou Xiaoshan (HGH) — 1.5 hours by car. Direct flights from many Asian and selected European hubs. Useful third option.

Cixi central district — 4-star options 15 minutes from the factory, walking distance to dinner restaurants. Recommended for buyers staying 1–2 nights for a focused factory visit.
Ningbo city — 5-star options 40 minutes from the factory; daily shuttle between hotel and factory at 08:00 and 17:00. Recommended for longer stays combining factory visit with broader sourcing trip in Ningbo / Shanghai.
Bookings handled by the export desk on request — advance booking 5+ working days.

Visa Invitation Letter

Chinese business-visa invitation letter (PDF) issued on request — standard document required by most embassies for the M (business) visa. Letter includes Shenghe's company registration details, the visitor's passport details, the purpose of visit (factory tour for procurement / OEM / ODM discussion), and the dates of intended stay. Letter is signed and stamped; sent by email PDF, hard copy via DHL / FedEx on request. Most embassies issue M-visa within 5–10 working days of application.

Airport Pickup & Driver

Driver at the arrivals hall on the agreed date and time, holding a sign with the visitor's name. Direct transfer to the hotel (or to the factory if same-day). English-speaking host travels with the driver for first-time visitors. Pickup logistics confirmed in the visit-confirmation email — flight number, arrival terminal, mobile number for the driver, mobile number for the host. Reverse pickup (hotel → airport at end of visit) handled the same way.

Local Transport & Logistics

Cixi-Ningbo-Shanghai region has excellent road and high-speed rail links. Many buyers combine the Shenghe factory visit with broader sourcing — same-day visits to other Ningbo suppliers, weekend in Shanghai before the long-haul return. Export desk can recommend local restaurants, dinner meeting venues, and weekend itinerary on request. Cixi has good local food culture — Ningbo cuisine, fresh seafood, traditional restaurants near the factory area.

Group Visits & Audits

Group visits (3+ visitors) accommodated with advance booking — meeting room sized for 8 attendees on the first floor, larger groups on request. Multi-day audits (ISO 9001 audit, social compliance audit, capacity verification audit) supported with 2–3 weeks notice so the QA team can prepare the document set. Visiting auditors typically stay 1–3 days; coordination with the buyer-side QA team and the audit firm (SGS / BV / Intertek / TUV) handled by the export desk.

Third-Party Audits — Welcomed, Accommodated

SGS / BV / Intertek / TUV All On Site Before.

Procurement teams running formal supplier qualification programmes typically commission a third-party audit before the first PO and a re-audit every 12–24 months thereafter. Shenghe welcomes these audits — no blocking, no surprise fees, no document gating.

ISO 9001 Quality Audit

Common audit type covering supplier qualification list, in-process inspection records, calibration records, non-conformance handling, batch traveler samples, complaint-handling 8D reports. Document set is pre-organised and reviewed by the QA team in advance of the audit. Auditor walks the production line to verify that the documented procedures match the floor reality. Typical 1-day on-site for a focused audit, 2–3 days for a full-system audit.

Social Compliance Audit

BSCI / SA8000 framework audits covering working hours, wage records, safety procedures, accommodation (where applicable), grievance mechanism, child-labour and forced-labour prevention. Document set includes HR records, payroll samples, fire-safety certificates, work-permit records. Common audit firms: SGS, BV, Intertek. Typical 1–2 days on-site.

Capacity Verification Audit

Production-capacity verification — buyer's QA team or third-party auditor checks claimed monthly capacity against actual production records, equipment uptime, headcount on shift, raw-material throughput. Useful for buyers committing to large recurring orders that would stress a smaller factory's capacity. Typical 1 day on-site; document set includes 6-month production records, equipment maintenance log, shift schedule.

Sample QA Verification

Buyer's QA team or third-party inspector verifies a buyer-supplied sample against the production batch — same SKU, same modification recipe, same QA protocol. Common before first PO release, especially for medical / EU-regulated / high-stakes applications. Sample teardown on the assembly station, dimensional check on calibrated equipment, electrical test on dyno bench, dielectric strength check, lot traceability check.

Pre-Shipment Inspection (PSI)

AQL-based inspection of a finished production batch before container loading — random unit selection per AQL 1.0 plan, dimensional + electrical + cosmetic check against PI, packaging and labelling check, container-loading photo. Run by buyer or third-party inspector; Shenghe coordinator on the factory side handles booking and access. Typical 0.5–1 day on-site. Inspection report shared with both sides; B/L copy issued after sailing.

Audit Cost & Logistics

Audit cost on the buyer side (audit firm fees + travel). Shenghe provides the access, the document set, and the time of the engineering / QA team — at no charge. No audit-blocking, no document gating, no surprise fees on the factory side. Audit booking handled via the export desk; common audit firms have visited multiple times before so onboarding is fast. NDA on audit findings supported.
