About Electric Motors
When replacing a motor, use the information on your motor’s nameplate to guide your selection.

Brushless DC Motors
Since there are no brushes to add weight and friction, these motors can achieve a higher torque-to-weight ratio, faster speeds, and better efficiency than DC motors with brushes. All motors require a driver (sold separately) to operate.
Round-face motors come with a connector that was used to test the motors during the manufacturing process. Before you can wire these motors to the terminals on their required driver, you will need to cut off the connector.
Drivers control the speed and direction the motor spins. To program the driver, connect it to your computer with a mini USB cord (sold separately) and use the free downloadable software to enter your speed and acceleration parameters. No coding is necessary.

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.

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).
