Three-phase asynchronous motor is good or bad, the most important thing is to look at the raw materials, the second is the processing technology, the technical level of the worker's operation is skilled, the quality of the motor is also very great, there is an important factor is the formation of several important parts of the motor, then the following Senli motor Xiaobian will take you to understand the following simple.

       The stator core is a part of the magnetic circuit of the motor, generally composed of0.35-0.5A millimeter-thick silicon steel sheet with an insulating layer on the surface is punched and laminated, and a uniform distribution of slots is punched in the inner circle of the core to insert the stator winding. The stator winding of a three-phase asynchronous motor, belonging to the circuit part, is fed by three-phase alternating current to generate a rotating magnetic field, which is separated by three in space120°The structure of electric Angle and team weight arrangement is connected by the same winding, and each coil of these windings is embedded in each slot of the stator according to a certain law. The frame is a fixed stator core and front and rear end cover to support the rotor, and plays the role of protection and heat dissipation.

       The rotor core is part of the magnetic circuit of the motor and the rotor winding is placed in the core slot, consisting of0.5The millimeter-thick silicon steel sheet is punched and laminated, and the silicon steel sheet has a uniform distribution of holes on the outside, which is used to place the rotor winding. The rotor core is usually punched by punching the inner circle of the backward silicon steel sheet with the stator core. Generally, the rotor core of small asynchronous motors is directly mounted on the shaft, and large and medium-sized asynchronous motors (rotor diameter in300~400The rotor core is pressed on the rotating shaft with the help of the rotor support.

       The rotor winding can cut the stator rotating magnetic field to generate induced electromotive force and current, and form electromagnetic torque to make the motor rotate, which is divided into squirrel cage rotor and wound rotor. The end cover plays a supporting role, the bearing can connect the rotating part and the stationary part, the bearing end cover can protect the bearing, and the role of the fan is to cool the motor.
