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

Speed-Control Motors
Maintain speed automatically. These motors come with a speed control with a feedback sensor that adjusts power to maintain your set speed. They combine the speed control characteristics of permanent magnet brushless DC motors with the convenience of AC power—an integrated inverter means they operate on 120 volts AC.
Motors are rated for continuous duty and mount at any angle. Shaft is keyed and comes with key stock. Use the switch on the speed control to set clockwise or counterclockwise rotation.
All have manual overload protection—an LED on the speed control indicates when the overload protection is triggered; use the switch to reset. Control also has an on/off switch and a speed adjustment knob. Panel mount the control up to 10 feet from the motor—it comes with a 10-ft. cable for connection.

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.

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.
View information about motors.
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.
