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

Base-Mount AC Motors


To get equipment moving, bolt the base of these motors to any flat surface and connect the shaft to your load. They’re rated for continuous duty, so they’re often used with equipment that requires constant power, like fans, pumps, and conveyors.
When pairing with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.
Motors with an IEC frame size meet international standards for electrical products. Their compact body fits in tight spaces.
Totally enclosed fan cooled (TEFC) enclosures don’t have vents, so they can be used in damp and dirty environments. They have an external fan that blows air over the outside of the enclosure to keep the motor cool. They’re not airtight, but since air isn’t flowing inside the enclosure, the motor won’t run as efficiently as it would in an open enclosure.

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. 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. 230/460V AC motors are inverter-rated, so you can adjust the speed with a motor speed control (not included).

Washdown Right-Angle AC Gearmotors



Run high-torque, low speed applications in cramped areas that are frequently hosed down. To save space, these transmit motion at a 90° angle from the the body of the motor, so they're positioned alongside equipment when mounted. They’re rated IP66 for protection from dust and water, and have a drain that allows internal condensation to escape, preventing corrosion. These TEFC (totally enclosed fan cooled) motors have an external fan that keeps them cool.
They’re inverter rated, so you can use them with a motor speed control (not included) to adjust the motor speed. Wire motors for clockwise or counterclockwise rotation; instructions are included.

Washdown AC Gearmotors
IP rated, these gearmotors stand up to high-pressure washdowns. They combine a motor with a speed reducer to lower speed while increasing torque. Their parallel shaft transmits motion inline with the motor.
Since they’re inverter-rated, you can adjust the speed with a motor speed control (not included). Wire these motors for clockwise or counterclockwise rotation; instructions are included.
Base-mount motors come with a base, so they can be secured to a flat surface. TEFC (totally enclosed fan cooled) enclosures protect against dirt, dust, and moisture. An external fan blows air on the enclosure to keep it cool. Motors rated IP66 have a labyrinth drain plug that keeps water out while letting condensation escape.

Right-Angle AC Gearmotors



A motor and speed reducer in one, these gearmotors have hypoid gears for energy-efficient operation. You can use them to turn a shaft on your equipment or add a keyed shaft (sold separately). Wire for clockwise or counterclockwise rotation; instructions are included. Gearmotors meet IP54 for protection from dust and splashed water. They're inverter rated so you can use them with a motor speed control (not included) to adjust the motor speed.

Speed-Control AC Gearmotors




Start, stop, reverse direction, and control the speed of these gearmotors from the mounted keypad. Because you can fine tune output speed and direction, these gearmotors are often used in material processing and handling applications, such as controlling the speed of a mixer or conveyor. These gearmotors are both a motor and speed reducer in one to lower speed while increasing torque. All transmit motion inline with the motor. Secure them to flat surfaces with the base mount. These gearmotors have a TEFC (totally enclosed fan cooled) enclosure that protects better than ODP (open drip proof) enclosures. They are not airtight but can be used in dirty, dusty, and damp environments. To keep the motor cool, they have an external fan that blows air over the outside of the motor.

Speed-Control Right-Angle AC Gearmotors




A good solution for tight spaces, these gearmotors let you control the start, stop, rotation direction, and speed while transmitting motion at a 90° angle from the motor, so you can mount them alongside your application. They combine a motor with a speed reducer to lower speed while increasing torque. All have a mounted keypad to make changes to the integrated speed control. Mount them to flat surfaces using their base. These gearmotors 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.
