High Torque Gear Motor 12V 500RPM 25GA-370 – 25mm Metal Gear DC Motor
VAT inclusive; Computed calculations added locally.
Overview
The 25GA-370 12V 500RPM DC Gear Motor is a compact geared motor designed for applications that require a combination of useful torque, moderate speed, and a small mechanical footprint. Its 25mm diameter gearbox makes it convenient for robot cars, automated mechanisms, and other space-constrained projects.
The gearbox uses metal gears for a sturdy mechanical construction, while the output shaft incorporates metal bushings to support smooth operation and wear resistance. The motor has a 4mm diameter shaft and a compact cylindrical body, making it easy to integrate with compatible wheels, couplers, and mechanical assemblies.
At its rated 12V supply, the motor is specified for 500RPM, with a rated torque of 0.5 kg-cm and a listed stall torque of 2 kg-cm. Actual speed, torque, and current consumption will vary depending on the applied mechanical load and operating conditions.
This motor is suitable for robotics, smart cars, automation equipment, mechanical prototypes, electronic locks, small conveyor mechanisms, and DIY projects requiring a compact 12V geared motor.

Product Technical Information
Technical Details
The High Torque Gear Motor 12V 500RPM 25GA-370 combines a compact 25mm gearbox with a metal gear train and 4mm D-shaped output shaft. It is designed for projects where a small motor with useful mechanical torque is required.
The metal gearbox and shaft bushings provide a robust construction for general-purpose mechanical applications. The motor can be integrated with wheels, couplers, pulleys, linkages, and other compatible mechanical components.
With a rated speed of 500RPM at 12V, it is particularly useful for small mobile robots and mechanisms that need more speed than low-RPM gear motors while still benefiting from gearbox-generated torque.

How to Use
- Connect the motor to a suitable 12V DC power source through an appropriate motor driver or switching circuit.
- Connect the motor driver output to the motor terminals.
- Reverse the motor terminal polarity to reverse the rotation direction when using a suitable DC motor driver.
- Attach a compatible wheel, coupler, pulley, or mechanical load to the 4mm D-shaped shaft.
- Ensure the mechanical load does not exceed the motor's practical torque capability.
- Avoid prolonged stall or locked-rotor operation because the motor can draw substantially more current and generate heat.
Important Notes
- This is a 12V DC motor; use an appropriate power supply and motor driver.
- Do not connect the motor directly to a microcontroller GPIO such as Arduino, ESP32, or Raspberry Pi.
- The 500RPM rating applies to the specified operating condition; actual speed decreases as mechanical load increases.
- The listed 2 kg-cm stall torque represents a stall condition and should not be treated as a continuous operating torque.
- Prolonged stall operation can cause excessive current draw, heating, and motor or gearbox damage.
- Use a motor driver with suitable current capacity and flyback protection.
- The shaft diameter is approximately 4mm; verify wheel/coupler compatibility before installation.
- Actual current consumption depends on load, friction, supply voltage, and motor condition.
- Product dimensions and weight may vary slightly between batches.
- Please allow approximately 5% measurement deviation due to manual measurement.
- Product images are for illustrative purposes only and may differ from the actual product.
