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

Direct-Drive Fan Motors
Since they have fewer moving parts, you can use these direct-drive motors to build fans that require less maintenance than fans with belt-drive motors. Mount them directly to a fan column.

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.
