An asynchronous motor using a single-phase AC power supply is called a single-phase asynchronous motor. Because single-phase asynchronous motors only need single-phase alternating current, they are easy to use and widely used, and have the advantages of simple structure, low cost, low noise, and little interference to radio systems, so they are often used in household appliances and small power machinery with low power. Among them, such as electric fans, washing machines, refrigerators, air conditioners, range hoods, electric drills, medical equipment, small fans and household water pumps. Since the single-phase voltage in China is 220V, and the single-phase voltage in foreign countries is 120V in the United States, 100V in Japan, and 230V in Germany, Britain, and France, it is necessary to pay attention to whether the rated voltage of the motor is the same as the power supply voltage when using foreign single-phase asynchronous motors.
Single-phase asynchronous motor consists of stator, rotor, bearing, casing, end cover, etc. Single-phase asynchronous motors are often made into small motor equipment. Its motor capacity is very small, and it only needs to be powered by single-phase AC power. As a driving motor, the power of single-phase asynchronous motors only needs a few watts, tens of watts or Several hundred watts.
Single-phase asynchronous motors have low power and are mainly made into small motors. It has a wide range of applications, such as household appliances (washing machines, refrigerators, electric fans), power tools (such as hand drills), medical equipment, automated instruments, etc.
