THREE PHASE SEQUENCE

Three phase electric power systems have at least three conductors carrying voltage waveforms that are 2π/3 radians offset in time.

A Three Phase Wave

The sinusoidal functions or in waves has two different, but closely related meanings. One is the initial angle of a siusoidal function at its origin and is sometimes called phase offset.

Three Phase AC generators

The principles of a three phase generator are basically the same as that of a single phase generator, except that there are three equally spaced windings and three  output voltages that are all 120 degrees  out of phase with one another.

Three Phase Ac Motor

The Ac induction motor is a rotating electric machine designed to operate from a three phase source of alternating voltage. The stator is a classic three phase stator with the winding displaced by 120 degrees.
