Brief description of electromagnetic vibration and noise of asynchronous motor
Introduction to Asynchronous Motors There are many types of motors and there are many classification methods. For example, according to the movement mode, there are transformers at rest, and linear motors and rotary motors are moving. Linear and rotary motors continue to be classified according to the nature of the power supply, as well as DC motors and AC motors. The AC motor can be divided into two categories: asynchronous motor and synchronous motor according to the relationship between running speed and power frequency. The classification can be further subdivided. In view of the fact that linear motors are less used, the above classification results can be summarized as:
An asynchronous motor is an AC motor, also called an induction motor, which is mainly used as a motor. Asynchronous motors are widely used in industrial and agricultural production, with capacities ranging from a few kilowatts to several thousand kilowatts. Increasingly popular household appliances, such as single-phase asynchronous motors in washing machines, fans, refrigerators, and air conditioners, range in size from a few watts to several kilowatts. In the high-tech fields such as aerospace and computer, control motors are widely used. Asynchronous motors can also be used as generators, such as small hydropower plants, wind turbines or asynchronous motors.
Asynchronous motor stator phase numbers are single-phase and three-phase. The three-phase asynchronous motor rotor structure has two kinds of cage type and winding type, and the single-phase asynchronous motor rotor is cage-shaped. The asynchronous motor is mainly composed of a stationary stator and a rotating rotor. There is an air gap between the stator and the rotor, and an end cover supports the rotor at both ends of the stator.
