Can You Speed Control A Capacitor Start Motor. I would like to be able to control the speed of the motor through use of a rheostat without significant loss of power. i have an old dayton 1/3 hp 1725 rpm capacitor start 120v motor that i am trying to put into use as a bench grinder/buffer. If you try to reduce the fan speed below the centrifugal switch s cut in. a start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 70 to 80 % of the full speed. I have a single phase duct fan that that run by a capacitor and its running too fast.
motor start capacitor is an electrolytic capacitor connected in series with auxiliary winding, which is switched off once motor picks up speed to near 70 percent of. I found a similar topic here: Makes no sense using vfd. Can You Speed Control A Capacitor Start Motor Cap start motors usually have a centrifugal switch that drops out the start capacitor at about 2 3 3 4 of full speed. On a mechanical, linear load, the. 1 i would like to control the speed of my psc induction motor.
