Compact Square-Face 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.

Compact Round-Face DC Gearmotors
Power small machinery in spaces where other gearmotors won’t fit. Gearmotors pair a motor with a speed reducer to lower speed while increasing torque.
To control motor speed, motor controls are also available. To convert AC power to DC power, see AC to DC transformers.

Extended-Life Compact Round-Face DC Gearmotors
Power small machinery in spaces where other gearmotors won’t fit. Gearmotors pair a motor with a speed reducer to lower speed while increasing 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.
Gearmotors have ball bearings that withstand heavier loads than gearmotors with sleeve bearings for a longer service life.

Base/Face-Mount Compact AC Gearmotors
Sized for small spaces, these gearmotors mount from the base or face for flexibility to fit in tight locations. Each has a motor matched with a speed reducer to lower speed while increasing torque. An optional plastic fan is included to improve cooling when using the gearmotor in a clockwise direction.
To reverse the direction of the gearmotor, loosen the mounting screws, remove the stator, and rotate it 180°. You’ll also need to replace the original fan blades with fan blades for counterclockwise shaft rotation (sold separately).
