12V DC Winch Motor Specifications
The SUNROAD 12V DC winch motor (model 12505) is a 2.0 kW brushed DC motor for vehicle winches and short-duty traction loads. It is manufactured by Zhejiang Sanrong Electric Motor Co., Ltd. in Ningbo, China.
Power, RPM and Duty Cycle
Model 12505 runs at 12 V DC, 2400 RPM, 2000 W output, 305 A rated current and 9 N·m rated torque. Insulation class is F. The duty cycle is S2 = 1 minute, which matches typical auto-winch pull cycles rather than continuous industrial running. Enclosure rating is IP54.
If you need a 24 V winch motor, SUNROAD also supplies a 24 V 2.5 kW 2500 RPM electric winch motor on the same application line.
Applications
This 12V DC winch motor is used on automotive and off-road winches, ladder trucks, vehicle tail-stock / tail-lift equipment, and other short-duty special equipment where high current and high starting torque matter more than continuous running.
OEM Winch Motor Options
Minimum order is 100 pcs. Standard pack is 100 pcs per export pallet. Custom shaft, rotation, 12 V / 24 V voltage, and connector options are available for winch OEM programs. Send the winch drum and gear ratio if you need a pulling-force curve with the quotation.
FAQ
What is the winch motor RPM of model 12505?
2400 RPM at 12 V DC rated load.
Can this motor run continuously?
No. Duty is S2 = 1 minute. It is designed for intermittent winch pulls.
What is the waterproof rating?
IP54 on model 12505. Other SUNROAD winch motors (for example 12290 and 39332) are published at IP66.
What is the MOQ?
100 pcs. Ask sales for drawings, a sample plan, and OEM lead time.

Understanding Winch Motor RPM
Winch motor RPM (revolutions per minute) is one of the most misunderstood specifications in vehicle winch design. A higher RPM does not always mean a faster winch, because the winch drum speed depends on both motor RPM and the gear reduction ratio.
Typical winch motor RPM ranges:
| Motor Type | No-Load RPM | Rated Load RPM | Common Applications |
|---|---|---|---|
| 12V DC Winch Motor (2.0kW) | 3,200 to 3,600 | 2,200 to 2,600 | ATV/UTV winches, 4x4 recovery |
| 24V DC Winch Motor (2.5kW) | 3,000 to 3,400 | 1,800 to 2,200 | Truck winches, industrial pulling |
| 24V Hydraulic DC Motor | 2,800 to 3,200 | 2,500 to 3,000 | Hydraulic power units, liftgates |
| Industrial Winch Motor (12V/24V) | 2,500 to 3,000 | 1,500 to 2,000 | Wreckers, car carriers, tow trucks |
The SUNROAD model 12505 12V DC winch motor delivers 2,400 RPM at rated load (9 Nm, 2.0 kW output). When paired with a typical 150:1 planetary gear reduction, this produces a drum speed of approximately 16 RPM, enough to pull 8 meters of cable in about 30 seconds under load.
When comparing winch motors, always look at rated-load RPM, not no-load RPM. No-load RPM is a marketing number; rated-load RPM determines real pulling speed.
How to Select the Right Winch Motor
Selecting a winch motor requires matching four parameters:
1. Voltage. 12V for passenger vehicles and ATVs; 24V for trucks, buses, and industrial equipment. 24V systems draw half the current for the same power, reducing cable gauge and heat.
2. Power output. Calculate required pulling force multiplied by line speed, divided by (gear efficiency multiplied by drum efficiency). A 4,000 kg winch pulling at 5 m/min requires approximately 3.3 kW of motor output.
3. Duty cycle. Winch motors are designed for intermittent duty (S2 or S3). If your application requires continuous pulling, specify a motor with a higher duty cycle rating or add forced ventilation.
4. Mounting. Standard winch motor mounting patterns include 4-bolt (80mm or 100mm BCD) and 2-bolt configurations. Confirm the mounting pattern before ordering.
Sanrong application engineers can help you size the correct motor. Provide the vehicle GVW, intended winch capacity, gear ratio, and available battery capacity.
Winch Motor Maintenance and Troubleshooting
To maximize winch motor service life:
- Keep the motor vent holes clear of mud, dust, and debris
- Inspect brushes every 50 hours of operation; replace when worn below 8mm
- Check terminal connections monthly; loose terminals cause voltage drop and overheating
- Avoid exceeding the rated duty cycle; continuous operation beyond 1 minute causes thermal damage
- Store the winch with the drum clean and lightly oiled to prevent corrosion
Common issues and solutions:
Slow pulling: usually caused by low battery voltage or worn brushes. Check battery state of charge and replace brushes if below minimum length.
Motor runs hot: exceeded duty cycle or insufficient gear lubrication. Allow cool-down period and check gearbox oil level.
Intermittent operation: check brush spring tension and commutator condition. Clean commutator with fine sandpaper if grooved.
Excessive noise: worn bearings or misaligned armature. Replace bearings and check armature balance.
Sanrong provides replacement brush kits, bearings, and complete repair services for all winch motor models.
