Single-phase motors generally refer to low-power single-phase asynchronous motors powered by a single-phase AC power supply. It is also called a single-phase induction motor. This kind of motor usually has two-phase windings on the stator, and the rotor is of ordinary squirrel cage type. The distribution of the two-phase windings on the stator and the different power supply conditions can produce different starting characteristics and operating characteristics.
Single-phase motors have a large production volume and are closely related to people’s daily lives. Especially with the improvement of people’s living standards, the consumption of single-phase motors for household appliances is also increasing.
