Constant-Speed AC Gearmotors



Achieve precise, constant speed for timing and positioning applications. Also known as synchronous gearmotors, these gearmotors use a frequency of 50/60 Hz to maintain speed and torque.

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.
