DC Gear Motor — Brushless And Brushed DC Gear Motors, 12V To 110V, 50W To 10kW.

This page is the category catalog for Shenghe's DC gear motor product line — bridging the broader gear motor Hub (which browses by gearbox type across DC and AC) and the individual voltage-specific SKU pages. Two motor commutation styles live under "DC gear motor": (1) brushless DC (BLDC) gear motors — electronically commutated, longer service life, higher efficiency, the dominant choice for continuous-duty industrial applications above 100W today; (2) brushed DC gear motors — mechanically commutated with carbon brushes, simpler control, lower upfront cost, still cost-competitive in low-volume consumer products or intermittent-duty equipment below 100W. Both ride on the same four in-house gearbox families (planetary, worm, helical / spur, right-angle), use the same 20CrMnTi case-hardened gear steel, the same lithium-complex grease, and the same AGMA Q9–Q11 quality grade — the gearbox doesn't care which motor type drives it. What changes between BLDC and brushed-DC is service life, efficiency, control sophistication and upfront cost. The DC-vs-AC decision section below covers when to pick DC over AC induction at all; the BLDC-vs-brushed-DC section covers the choice within the DC family.

DC Gear Motor Category — Bridge Between Hub And SKUs

One Page To Decide DC-vs-AC, BLDC-vs-Brushed, And Pick The Voltage.

Most users typing "DC gear motor" into a search engine are at one of three decision points: (1) deciding between DC and AC for a new design — see the DC vs AC table below; (2) deciding between BLDC and brushed DC for an existing DC application — see the BLDC vs brushed DC table; (3) already committed to DC and just need to find the right voltage × power × gearbox combination — jump to the voltage matrix and the gearbox-type selector. This page covers all three decision points in one place; the individual voltage and gearbox SKU pages cover the per-product spec detail.

Decision 1 — DC Gear Motor vs AC Gear Motor

When To Pick DC Over AC Induction.

AC induction gear motors used to be the default for industrial fixed-speed duty (conveyor, pump, fan, mixer). For variable-speed duty, modern BLDC gear motors have displaced AC induction in most mid-power applications because BLDC + matched controller delivers better efficiency, finer speed control, smaller package and battery-friendliness in one unit — without needing a separate VFD. The table below frames the choice on the dimensions that matter for new designs.

DimensionDC Gear Motor (BLDC + Brushed DC)AC Gear Motor (Induction + VFD)
Power source Battery, DC bus, AC mains via rectifier — works on 12V to 220V DC AC mains 110V / 220V / 380V / 480V single or three-phase
Best for mobile / battery applications ★★★ — AGV, e-mobility, mobile robotics, off-grid solar all DC-native Not practical — needs heavy DC-to-AC inverter for battery operation
Speed control Built-in (PWM / analog 0–10V / RS485) on BLDC; brushed DC via voltage adjustment Needs separate VFD (variable frequency drive) — extra component cost + cabinet space
Efficiency at part load 85–92% across the speed range (BLDC); 70–80% (brushed DC) Drops below 70% at light load on AC induction — VFD adds 5–8% loss
Package size per watt Smaller / lighter — BLDC permanent magnet rotor is power-dense Larger — induction motor needs rotor cage, slip control, larger frame
Microcontroller integration ★★★ — PWM signal directly drives BLDC controller; RS485 / CAN for digital control Needs PLC + VFD with Modbus or analog interface — more integration overhead
Power class 50W to 10kW standard at Shenghe; up to 15kW on ODM Practical range 100W to many MW — AC wins for >15kW industrial duty
Upfront cost BLDC + controller premium ~20–40% over AC induction + VFD at <1kW; parity at 1–5kW Cheaper at >5kW; basic fixed-speed AC induction without VFD is cheapest of all
Maintenance BLDC: 20,000+ hour life, no brush dust, no commutator wear — almost zero scheduled maintenance AC induction: very robust, mature tech, bearings the main wear item — also low maintenance
Best for fixed-speed industrial Acceptable but overkill — AC induction wins on cost ★★★ — fixed-speed conveyor, pump, fan, mixer at >1kW
Best for variable-speed automation ★★★ — modern industrial automation, AGV, robotics, packaging machinery Workable with VFD but adds cabinet space, cost, and control complexity

Rule of thumb: if your application is battery-powered, mobile, variable-speed below 10kW, or microcontroller-driven — pick DC gear motor (BLDC for continuous duty, brushed DC for intermittent or cost-sensitive). If your application is mains-powered, fixed-speed, industrial duty above 5kW — AC induction + simple starter is hard to beat. Mid-range (1–5kW variable-speed industrial) is the contested zone where Shenghe's BLDC gear motor + matched BLD6010 controller wins on package size, efficiency and integration simplicity.

Decision 2 — BLDC vs Brushed DC Gear Motor

Within The DC Family, Which Commutation Fits Your Duty Cycle.

Once the DC vs AC decision is settled, the next choice is BLDC (brushless DC) or brushed DC. Same gearbox, same housing, same shaft — the motor side differs. The breakeven sits at duty cycle: continuous-duty applications above 2,000 hours/year favour BLDC's longer life and higher efficiency; intermittent-duty consumer or hobby applications below 2,000 hours/year often pay off brushed DC's lower upfront cost.

DimensionBLDC Gear MotorBrushed DC Gear Motor
Commutation Electronic — controller switches MOSFETs based on Hall sensor or encoder feedback (sensorless option for low-startup applications) Mechanical — carbon brushes on a copper commutator rotate the current path inside the motor
Service life (continuous duty) 20,000+ hours; bearings and oil seals are the main wear items 2,000–5,000 hours; brushes wear out and need replacement, commutator surface erodes
Peak efficiency 85–92% (full-load) — efficiency stays high across speed range 70–80% (full-load) — drops at low speed due to brush friction and commutation losses
Brush dust / particulate emission None — sealed motor Yes — carbon dust generated, problematic in clean-room, food, medical, semiconductor environments
Audible noise Lower (smooth electronic commutation, lower torque ripple) Higher (mechanical brush contact, broader frequency spectrum)
Speed control method PWM via controller, RS485 / CAN / analog 0–10V — fine control across full speed range with closed-loop feedback Voltage adjustment (linear or PWM external controller) — open-loop, no inherent feedback
Torque ripple Lower with FOC drive on Shenghe BLDC servo; standard six-step commutation has moderate ripple Higher due to discrete commutation steps as brushes cross commutator segments
Upfront cost (motor + drive) 30–60% premium over equivalent brushed DC motor + simple PWM controller Lower — motor + basic PWM controller costs less than BLDC + matched controller
Total cost of ownership (5-year continuous duty) ★★★ — premium pays back inside 12–18 months on continuous duty >2,000h/year (energy savings + brush replacement avoidance + downtime) Higher TCO at continuous duty due to brush replacement cost, downtime, and 10–15% higher energy cost
Best-fit applications Industrial automation, AGV traction, packaging machinery, conveyor (continuous duty), robotics, medical equipment, HVAC fans, automatic doors Consumer products, hobby applications, intermittent-duty equipment, low-volume builds where brushes can be replaced as scheduled maintenance

Application Sections

Where DC Gear Motors Get Used Every Day.

The six application contexts that drive most of Shenghe's DC gear motor production. Each section links to the application-specific page for deeper context on duty cycle, environmental envelope and matched controller pairing.

Conveyor & Sortation

BLDC gear motor (24V or 48V, 200W–1500W) with planetary or right-angle gearbox for continuous-duty industrial conveyor lines, sortation systems, packaging-line transport. Variable-speed drive lets line speed match upstream/downstream throughput dynamically. See BLDC motor for conveyor → for the application page.

AGV / AMR Traction & Steering

BLDC gear motor (24V or 48V, 250W–1500W) with planetary gearbox for AGV / AMR traction drives. 48V/750W and 48V/1000W are the most-asked stocked SKUs; see 48V 750W BLDC → and 48V 1000W BLDC → for the bare-motor side, then pair with planetary gearbox. See BLDC motor for AGV → for application context.

Robotic Actuators & Joints

BLDC servo gear motor with encoder feedback, low-cogging design, planetary gearbox for robot joints. Hollow-shaft option for cable routing on 6-axis arms. Closed-loop position/torque control via BLDB6010 servo controller with FOC. See BLDC servo motor → and brushless motor for robotics →.

Automatic Doors, Lifts & Barriers

BLDC or brushed-DC worm gear motor for automatic doors, residential lifts, vehicle barriers and conveyor stops — self-locking under load lets the door / lift / gate hold position with the motor de-energised, no mechanical brake needed. 24V or 48V, 100W–500W typical. See worm gear motor →.

Packaging Machinery

BLDC gear motor with helical or spur gearbox for continuous-duty packaging machines — labelling, capping, sealing, palletising. Low audible noise (matters in food / pharmaceutical packaging halls), variable-speed for SKU changeover, IP54 standard with IP65 upgrade for washdown environments. NSF H1 food-grade lubricant on request.

Solar Tracking & Lifting Equipment

Low-power BLDC gear motor (12V or 24V, 50W–200W) with high-ratio gearbox (200:1 to 1000:1) for slow, high-torque positioning — solar trackers, scientific instruments, lifting stages, satellite dishes. See brushless motor for solar tracker → for solar-specific application detail.

Why Source DC Gear Motors From Shenghe

Six Reasons Procurement Teams Stay Past The First Order.

The reasons distributors and OEM procurement teams come back for a second container. Not aspirational copy — the operating reality of working with a direct-factory DC gear motor manufacturer at Cixi, Ningbo.

1. BLDC + Brushed-DC Under One Roof

Same factory builds both. The 4 gearbox families, the gear material, the lubrication standards and the assembly procedures are identical across BLDC and brushed-DC variants — only the motor commutation changes. Buyers running mixed catalogs (BLDC for industrial duty + brushed DC for consumer products) source from one supplier with one PO and one QA standard.

2. Direct Factory — No Trader Margin

Shenghe is the factory. Quote price = factory FOB, not factory price + 12% sourcing fee. Distributors moving from a trading-company supplier typically see 8–15% landed-cost reduction once they switch to direct. See /bldc-motor-wholesale/ for the published volume tier pricing.

3. Matched Motor + Controller Kit (BLDC)

BLDC gear motors ship with the matched controller (BLD22010 for 24V/36V, BLD6010 for 48V/72V/110V, BLDB6010 servo) pre-paired and tested together on the dyno bench at end-of-line — firmware parameterised against the motor's electrical spec + gearbox ratio, no field-tuning required.

4. Per-Unit Dyno Test Record

Every gear motor receives an end-of-line dynamometer test before packing — output rated torque, output peak torque, no-load output speed (verifying actual ratio against spec), no-load motor-side current, temperature rise, audible noise, planetary backlash where applicable. Test record sticker on the unit; lot record retained on file under ISO 9001 procedures.

5. Audit-Welcomed Factory

ISO 9001 / CE / RoHS audit-ready. Third-party audits (SGS / BV / Intertek / TUV) accommodated with 2–3 weeks notice — ISO 9001 quality audit, social compliance BSCI/SA8000, capacity verification, sample QA verification, pre-shipment inspection. Audit cost on buyer side; Shenghe provides access and documentation, no surprise fees. Visit booking at /bldc-motor-factory/.

6. 20 Minutes From Ningbo-Zhoushan Port

World's #1 cargo throughput port for 13 consecutive years. Daily container drops, no inland-haul lottery between an inland factory and the port of loading. The port-proximity advantage shows up in landed-cost calculations as tighter, more predictable transit time — not a glamour sales line, just geography.
