Description

Technical Field

[0001] The utility model relates to the technical field of synchronous motors, in particular to a synchronous motor. Background Art

[0002] The synchronous motors currently on the market usually mainly consist of two parts: the stator and the rotor, in which the rotor is placed in the center of the stator core. Under the action of the alternating magnetic field of the stator, the rotor can drive a certain load to rotate through the rotating shaft. The greater the load applied to the synchronous motor, the more difficult it is to start, and the greater the rated power of the synchronous motor required. Therefore, the width of the magnetic circuit formed by the stator core and the radial magnetization length of the magnet are also greater.

[0003] During the use of existing synchronous motors, when it is necessary to fine-tune the installation position of the motor, the screws used to fix the motor must be loosened first. The screws used to fix the motor are generally composed of a nut and a nut, and two wrenches are required to operate. This operation method is difficult and is not suitable for popularization.
