Base-Mount AC Brake Motors
Unlike standard AC motors, these motors have an integrated brake that activates after a power loss to hold your equipment in place. They’re often used with conveyors to stop them from moving backwards after a power loss, and with hoists to prevent them from dropping a load. Mount their base to flat surfaces. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock. These motors have a TEFC (totally enclosed fan cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They aren’t airtight, but they can be used in dirty, dusty, and damp environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

Face-Mount AC Brake Motors
A built-in brake engages to hold your equipment in place when these motors lose power, unlike standard AC motors. These motors are often used with conveyors to keep items in place after a power loss, and with hoists to prevent them from dropping a load. Also known as C-face motors, these bolt directly to your equipment. They’re rated for continuous duty, so they can run equipment that never turns off. Their shaft is keyed, and they come with a key stock. These motors have a TEFC (totally enclosed fan cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They’re not airtight, but they can be used in dirty, damp, and dusty environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

Base/Face-Mount AC Brake Motors
When these motors lose power, a brake engages to hold your equipment’s position, unlike standard AC motors. They’re often used with conveyors to keep items in place after a power loss, and with hoists to stop them from dropping a load. Mount them from the base or face. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock. These motors have a TEFC (totally enclosed fan cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They aren’t airtight, but they can be used in dirty, dusty, and damp environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

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.

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.
