Compact DC Gearmotors
Drive low-speed, high-torque applications in small spaces. Gearmotors combine a motor and speed reducer to lower speed and increase torque. Wire for clockwise or counterclockwise rotation.
Use a motor speed control (not included) to adjust the motor speed. To convert AC power to DC power, see AC to DC transformers.
Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.
Gearmotors with ball bearings withstand heavier loads than those with plain bearings for a longer life.
