Motor, generally referred to as motor, also known as motor, is a very common thing in modern industry and life. It is also the main equipment to change electric energy into mechanical energy. Motors are installed in cars, high-speed railways, aircraft, fans, robots, automatic doors, water pumps, hard disks and even our daily mobile phones. Many people who are new to motor or just learn motor driving knowledge may feel that motor knowledge is difficult to understand, and even have a big head when they see relevant courses, with the title of "credit killer". Now, through scattered sharing, novices can quickly understand the principle of AC asynchronous motor.

★ principle of motor: the principle of motor is very simple. In short, it is a device that uses electric energy to generate rotating magnetic field on the coil and drive the rotor to rotate. Those who have studied the law of electromagnetic induction know that the energized coil will rotate under force in the magnetic field. This is the basic principle of motor. This is the knowledge of physics in junior middle school.

★ motor structure: as everyone who has disassembled the motor knows, the motor is mainly composed of two parts, fixed stator and rotating rotor, as follows:

1. Stator (stationary part) stator core: an important part of motor magnetic circuit, on which stator winding is placed;

Stator winding: it is the coil, the circuit part of the motor, which is connected to the power supply to generate a rotating magnetic field;

Base: fix the stator core and motor end cover, and play the role of protection and heat dissipation;

2. Rotor (rotating part) rotor core: an important part of the magnetic circuit of the motor. The rotor winding is placed in the core slot;

Rotor winding: cutting the stator rotating magnetic field, generating induced electromotive force and current, and forming electromagnetic torque to rotate the motor.

Friends interested in motor stator and rotor iron core can pay attention to Yuma precision and update industry related knowledge from time to time.
