Single-phase motors generally refer to single-phase induction motors.

An induction motor powered by a single-phase AC supply is known as a single-phase induction motor. Because they require only single-phase AC power, these motors are convenient to use and widely applied. Furthermore, they offer advantages such as simple construction, low cost, low noise levels, and minimal interference with radio systems. Consequently, they are frequently utilized in low-power household appliances and small-scale machinery-examples include electric fans, washing machines, refrigerators, air conditioners, range hoods, electric drills, medical equipment, small blowers, and domestic water pumps. Since the standard single-phase voltage in China is 220V-whereas voltages in other countries vary (e.g., 120V in the U.S., 100V in Japan, and 230V in Germany, the UK, and France)-it is essential to verify that the motor's rated voltage matches the power supply voltage when using single-phase induction motors imported from abroad.

A single-phase induction motor consists of a stator, a rotor, bearings, a housing, end shields, and other components. These motors are typically manufactured as compact units with relatively low power capacities, requiring only a single-phase AC power source for operation. When serving as drive motors, single-phase induction motors typically require power outputs ranging from just a few watts to several tens or hundreds of watts.
