I have a customer that came to us, looking for a variable speed control for a 115V motor
He bought a 115V vibrator. The motor is a cap start. According to my understanding, it is not trustworthy, or maybe not even possible, to vary the speed of a single phase motor.
I read this thread

and it has strengthened my understanding.
Am I correct? Is there any new controls any one has heard of to do this or is it even electrically possible?
Any advice would be helpful. Thanks.
