Hi All,
With some people pushing 2 speed pumps for energy efficiency would it be possible to put a single speed pump on a rheostat or electronic dimmer (for motors) to control the pump speed or would this torch the motor.?
Thanks,
J.

Pump motors are induction type. Under load you can't really control the speed with a rheostat or dimmer. Under light load you can but it isn't recommended. A rheostat is just a variable resistor in series with the motor. Maybe another term is Variac which is a variable transformer where the output voltage is adjustable. No resistance element involved. A dimmer is a dual mode triac, solid state device that triggers on a controlled part of the AC cycle. They aren't compatable with motors or fluorescent lights. Multiple speed motors have a separate winding that is switched in for the low speed.
