WebMar 28, 2016 · Capacitors that allow a motor to start rotating are called start capacitors. Smaller motors usually have the start capacitor permanently connected in series to the secondary winding. Big motors require a larger capacitor to help them generate the starting torque, but they run more efficiently with a small capacitor in place, called run capacitor. WebFeb 16, 2024 · The caps provide the 3rd leg kick to start the motor spinning. The motor will be a generator making 3 phase. Your driven motors will only develop about 80% of fully rate power, but you rarely use the full rated power on most tools for other than a very short time. So don't pass up a great deal on a used tool just because it is 3 Phase.
