A single phase generator is an electrical device that produces a single alternating current (AC) waveform. It consists of a rotating coil of wire in a magnetic field, which produces a voltage as the coil is rotated. Single phase generators are typically used to power small electrical appliances, such as washing machines and refrigerators.
A three phase generator is an electrical device that produces three alternating current (AC) waveforms, each one 120 degrees out of phase with the others. It consists of three rotating coils of wire in a magnetic field, which produces three electric voltages as the coils are rotated. Three phase generators are typically used to power large industrial motors and machines.
