Split-Phase Induction Motor

By 22 July 2017

This is a single-phase split in two-phase currents for creating a two-phase condition.

Thus, phase splitting creates a rotating field. In the split-phase motor, an auxiliary winding in the stator is used for starting, with either a resistance connected in series with the auxiliary winding, known as the resistance start, or a reactor in series with the main winding, known as the reactor start.

The start winding of a split motor is made up of a few turns of a small diameter wire giving a high resistance and a low reactance.

They are used in small machines that require low torque.
