According to its different principles, AC motors can be divided into two categories: synchronous motors and asynchronous motors, the rotation speed of synchronous motors has a strict correspondence with the frequency of AC power supply, and the speed is strictly constant in operation; The rotational speed of the asynchronous motor varies slightly with the load.
According to the different phases of AC power supply, AC motors can be divided into two categories: single-phase and three-phase, and the most widely used is the three-phase asynchronous motor, which is due to the advantages of simple structure, low cost, sturdy and durable, easy to use and maintain. In the absence of three-phase power supply and some small power motors, single-phase asynchronous motors are widely used.
Three-phase asynchronous motors can be divided into two categories: squirrel cage type and winding type according to the different rotor structures, of which the squirrel cage type is the most widely used.

If the first circle is passed by direct current, a magnetic field will be generated, when the coils of the three poles of A, B and C are electrified in turn, then the three pairs of magnetic poles of A, B and C will take turns to generate a magnetic field to attract the rotor to rotate. First of all, there is a phase coil (set to phase A) to be energized, then the two teeth of the rotor are attracted by the magnetic pole A, and the rotor stays at the position of Figure 5-5a. >>>More
