**broken link removed** I have a milling machine with a 1 hp 3 phase motor that I want to run on 240 VAC single phase. I have L1 and L3 connected to 240 volts in my garage. If I temporarily connect a 90 MFD capacitor from L2 to one of the 240 VAC wires with a N.O. push button switch, then turn on the power switch and the motor starts. Motor runs good on 2 windings once I get it started. If the 90 MFD capacitor stays in the circuit the motor will buzz very loud. A smaller 30 MFD capacitor causes less buzzing. The motor runs at 2/3 it power rating running on 2 windings. Everything I read online says, keep a 30 MFD capacitor between the unused winding and one of the 240 VAC power lines but that does not seem to improve the performance of the motor it just buzzes and uses more electricity.
My question is about the capacitor in the first circuit. Do I really need a capacitor connected to the extra winding motor run good without it???
