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.
