What Is a Single-Phase Motor? A single-phase electric motor uses a single-phase power supply to convert electric energy into mechanical energy. It contains two wires (one hot wire and one neutral wire) and uses a single alternating voltage. Since it only generates an alternate field, it needs a capacitor for startup. Single-phase motors can ...
