China PMDC Motor Specifications
The SUNROAD PMDC motor (permanent-magnet brushed DC, model 101S-3-1) is a 230 W continuous-duty motor for sorting and intelligent-logistics equipment. It is manufactured by Zhejiang Sanrong Electric Motor Co., Ltd. in Ningbo, China.
Voltage, Speed and Continuous Duty
Model 101S-3-1 is rated 62 V DC, 1150 RPM, 230 W, 5.5 A and 2 N·m. Duty cycle is S1 (continuous). Insulation class B. Enclosure IP54. Because the field is a permanent magnet, the motor stays compact and is a typical PMDC motor factory choice for conveyor and sorter drives that run all shift.
Applications
This PMDC motor is used on parcel sorting equipment and intelligent-logistics lines. Related SUNROAD PMDC / brushed DC lines also cover gear-motor and pump-motor variants when the machine needs lower speed or higher torque.
OEM and Factory Options
Minimum order is 120 pcs. Standard pack is 120 pcs per export pallet. OEM options include shaft, rotation, 12 V / 24 V / other DC voltages, and adding a gearbox (PMDC gear motor). Send the load curve and mounting drawing for a factory quotation.
FAQ
What is a PMDC motor?
A permanent-magnet DC motor. The stator field comes from magnets, not a field winding, so the motor is smaller than a wound-field DC motor of the same torque.
What are the ratings of model 101S-3-1?
62 V DC, 1150 RPM, 230 W, 5.5 A, 2 N·m, S1, IP54.
Can this motor run continuously?
Yes. Duty is S1.
What is the MOQ from this PMDC motor factory?
120 pcs. Ask sales for drawings, samples, and OEM lead time.

Why Source PMDC Motors from a China Factory?
When global OEMs and equipment builders evaluate permanent magnet DC motor suppliers, China has become the default manufacturing base and for concrete reasons. Zhejiang Sanrong Electric Motor Co., Ltd. operates its own PMDC motor factory in Ningbo, a port city with direct access to Shanghai and Ningbo-Zhoushan, the world's busiest container port. This means shorter lead times, lower freight costs, and simpler export documentation compared with inland suppliers.
A China PMDC motor factory offers three structural advantages that Western contract manufacturers cannot match:
1. Vertical integration. Sanrong produces stator assemblies, permanent magnet rotors, gearboxes, and end caps in-house. Critical tolerances such as concentricity, air gap, and brush seating are controlled on the production floor rather than outsourced. This directly reduces field failure rates.
2. Cost transparency at volume. PMDC motor pricing is dominated by copper wire, magnetic steel, and lamination steel. A China factory with annual volume in the millions of units secures raw material at prices that low-volume European shops cannot obtain. For an OEM program above 5,000 units per year, the landed-cost gap typically ranges from 25% to 40%.
3. Engineering responsiveness. Chinese PMDC motor factories have learned to move fast. Sanrong's standard lead time for a modified PMDC sample is 10 to 15 working days; production tooling changes are typically completed within three weeks. This cadence matches the development cycles of automotive, medical, and industrial equipment customers.
PMDC Motor vs. BLDC Motor: How to Choose
One of the most common questions our engineering team receives is whether a brushed permanent magnet DC motor (PMDC) or a brushless DC motor (BLDC) is the right choice. The answer depends on four factors:
| Factor | PMDC Motor | BLDC Motor |
|---|---|---|
| Upfront cost | Lower (simple construction, no controller required) | Higher (requires electronic controller) |
| Maintenance | Brushes need replacement every 1,000 to 3,000 hours | Brushless, essentially maintenance-free |
| Speed range | Typically up to 6,000 RPM | Up to 50,000+ RPM |
| EMI / RFI | Brush arcing generates electrical noise | Low electromagnetic interference |
| Control simplicity | Direct voltage control | Requires PWM or field-oriented control |
| Best for | Intermittent duty, cost-sensitive apps, short lifecycle | Continuous duty, precision speed, long life |
Choose a PMDC motor when the application runs intermittently such as winches, actuators, and pumps, the bill of materials is cost-sensitive, and the design life is under 3,000 hours. Choose BLDC when the motor runs continuously, requires precise speed control, or must operate maintenance-free for 10,000+ hours.
Sanrong manufactures both technologies. If you are uncertain, send us the duty cycle, load profile, and ambient temperature. Our application engineers will recommend the most economical configuration.
Inside the Sanrong PMDC Motor Factory
Our Ningbo factory occupies 8,000 square meters of production space with four automated winding lines, two permanent magnet magnetization stations, and a dedicated test laboratory. Every PMDC motor undergoes:
- Armature dynamic balancing (G2.5 grade or better)
- 100% no-load current and speed testing
- 100% high-potential (hipot) dielectric testing at 500V AC for 1 second
- Load-point torque verification on sampled units
- Noise and vibration measurement in an anechoic chamber
Production capacity: 30,000 PMDC motors per month across all frame sizes. MOQ for standard catalog motors is 100 pieces; custom OEM programs start at 500 pieces with a dedicated production line.
Certifications: CE, RoHS, REACH. ISO 9001:2015 quality management system. Custom certifications including UL, CSA, and IATF 16949 are available for volume programs.
Additional Frequently Asked Questions
Q: What is the typical lead time for a custom PMDC motor?
A: Sample development takes 10 to 15 working days. Mass production lead time is 25 to 35 days after sample approval, depending on order quantity and material availability.
Q: Can you produce PMDC motors with custom voltage or shaft dimensions?
A: Yes. We offer custom voltages from 6V to 220V DC, custom shaft diameters, lengths, keyways, and D-flats. Custom mounting flanges and gearboxes are also available.
Q: What is the minimum order quantity?
A: 100 pieces for standard catalog models. For fully custom OEM designs, the MOQ is 500 pieces per model.
Q: Do you provide drawings and 3D models?
A: Yes. We provide 2D dimension drawings (PDF/DWG) and 3D STEP files for all custom programs before tooling begins.
Q: How are PMDC motors packaged for export?
A: Standard export packaging: anti-static bag plus foam insert plus corrugated carton plus plywood pallet. Custom packaging available per customer specification.
