Squirrel-cage three-phase asynchronous motor refers to a three-phase distributed winding on the stator of the motor and a cage guide bar on the rotor. Because the shape of the guide bar is similar to the squirrel cage, it is called the squirrel cage asynchronous motor. Here is a simple understanding with Senli Motor Xiaobian!

       The rotor is what distinguishes the squirrel-cage type from the winding type.Three-phase asynchronous motorThe rotating part of the rotor is composed of a rotor core, a rotor winding, a rotating shaft and a fan. The core of the rotor is also a part of the magnetic circuit of the motor, and is formed by superimposed silicon steel sheets with uniform grooves on the outer circumference, and is fixed on the rotating shaft. The rotor winding is placed in the wire slot of the rotor core.

       The core of the wound rotor is the same as the core of the squirrel cage rotor. The rotor winding is similar to the stator winding, which is wound by insulated wire and embedded in the rotor slot according to certain rules to form a three-phase symmetrical winding. It is named after its shape like a squirrel cage, and its structure is embedded in a copper strip as a conductor, and the two ends of the copper strip are welded with a short-circuit ring.

       Three-phase AC squirrel cage induction motor is widely used, the application of electromagnetic induction principle, mainly drag a variety of production machinery to run; In modern industrial and agricultural production, there are about70%～80%The mechanical transmission equipment is driven by it. This kind of motor is widely used because of its simple structure, reliable operation, convenient maintenance and cheap price.
