DC Gearmotors
Convert speed to torque to get the power you need—gearmotors are a motor and speed reducer in one. You can wire for clockwise or counterclockwise rotation; instructions are included. Gearmotors transmit motion inline with the motor.
To control motor speed, motor controls are also available. To convert AC power to DC power, see AC to DC transformers.

Right-Angle DC Gearmotors
A good solution for tight spaces, these gearmotors transmit motion at a 90° angle from the motor, so they’re positioned alongside your application when mounted. Gearmotors combine a motor and speed reducer to lower speed and increase torque.
To control motor speed, motor controls are also available. To convert AC power to DC power, see AC to DC transformers.
Gearmotors with a hollow body/removable shaft come assembled with a single-sided shaft for right-hand output. You can remove the shaft and turn it around for left-hand output, or you can replace it with a dual shaft (sold separately) to drive two processes at the same time. To monitor shaft rotation, you can pair this shaft with an encoder (not included).

Washdown DC Gearmotors
Rated IP55 with an epoxy-coated enclosure, these gearmotors drive low-speed, high-torque applications in areas that are subject to low-pressure washdowns. They combine a motor with a speed reducer to lower speeds while increasing torque. Since their shaft is parallel to the motor, they transmit motion inline with the motor. They have a TENV (totally enclosed nonventilated) enclosure that is similar to a TEFC (totally enclosed fan cooled) enclosure, except it doesn't have a fan. It relies on cooling from the air circulation created by the motor's motion instead.
You can wire the shaft to rotate clockwise or counterclockwise; instructions are included.

Washdown Right-Angle DC Gearmotors
Drive low-speed, high-torque applications in tight areas that are washed down. These gearmotors have an epoxy-coated enclosure and are rated IP55 to protect against water from low-pressure washdowns. They combine both a motor and speed reducer to lower speeds and increase torque. Since their shaft is at a 90° angle from their motor, they transmit motion alongside your application, so they take up less space than gearmotors with a shaft that's inline with their motor. They have a TENV (totally enclosed nonventilated) enclosure that is similar to a TEFC (totally enclosed fan cooled) enclosure, except it doesn't have a fan. It relies on cooling from the air circulation created by the motor's motion instead.
You can wire the shaft to rotate clockwise or counterclockwise; instructions are included. You can also switch the shaft's right-hand orientation to a left-hand orientation by removing the retaining covers, reversing the orientation, and then reassembling.
