A single-phase electric motor runs on a single-phase supply and is used in low-power applications. It offers a practical solution for homes, workshops and small businesses where a three-phase supply is not available.

Structure of the Single-Phase Motor

Single-phase motors use an auxiliary winding and a capacitor alongside the main winding to create a rotating magnetic field. The capacitor provides the phase difference needed to start.

Applications

Small water pumps, fans, compressors, washing and dishwashing machines and workshop machines run on single-phase motors. Power is usually in the 0.12–3 kW range.

Advantages

Being able to run from a standard single-phase outlet, simple installation and being economical are its main advantages. It is an ideal solution for low-power applications.
