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).

AC Gearmotors
Turn speed into torque with these AC-powered gearmotors—they combine a motor and a speed reducer into one. You can wire them for clockwise or counterclockwise rotation; instructions are included. The parallel shaft transmits motion inline with the motor.
Base-mount motors come with a base, so they can be secured to a flat surface. Face-mount motors bolt directly to your equipment. Base/face-mount motors give you the flexibility to mount directly onto equipment or to the included base.
TEFC (totally enclosed fan cooled) motors have an enclosure to protect them from dirt, dust, and moisture. An external fan blows air on the enclosure to keep them cool. TENV (totally enclosed non-ventilated) enclosures are similar to TEFC enclosures, except they do not have a fan. They rely on air circulation from the motion of the motor for cooling.
