What is an AC Fan Speed Controller?

AC Fan motors have two TRAICs (triode for alternating current) to meet variable speed requirements. These thyristors have three-terminal electronic components that conduct current in either direction when triggered. The TRIACs control the voltage of the motor.

eMotors Direct’s stock of AC motor fan speed controllers are designed to control the speed of AC fan motors easily. They provide infinite and precise variable speed control to permanent split capacitor motors, shaded pole motors, and universal motors, so you can run them in low, medium, and high-speed ranges. Most often applied to ceiling fans, commercial vent hoods, industrial blowers, and magnetic stirrers. They are found in the agricultural industry, controlling the speed of barn fans to help provide a more comfortable environment and necessary airflow/exchange.

Our AC motor fan speed controller category covers the wall-mounted fan speed controllers by KB Electronics. Designed to be mounted into a 2” x 4” electrical wall box, these controllers are easy to install and use. They are equipped with an on/off switch, a noise suppression filter, and a flame-retardant enclosure.
