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

Base-Mount AC Motors
Replace old base-mount motors to keep your equipment moving. Motors are rated for continuous duty and mount at any angle. You can wire for clockwise or counterclockwise rotation; instructions are included.
To use a motor with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.
Motors with a vibration-damping base have rubber rings between the base and enclosure to minimize vibration.
Motors with overload protection turn off in overload conditions to prevent motor damage. Automatic overload protection starts the motor automatically after it cools.

Pedestal Fan Motors
Build your own fan or replace a fan motor. Mount one of these motors directly to a fan column. Four 8-32 threaded mounting studs extend 1" for mounting a fan guard.

Note: When selecting a fan blade, be sure the rpm and hp are compatible and the shaft diameter of the blade matches the shaft diameter of the motor.
