[0002] A permanent magnet synchronous motor is composed of components such as a stator, a rotor, and an end cover. The stator is basically the same as that of an ordinary induction motor, and a laminated structure is adopted to reduce the iron loss during the operation of the motor. The rotor can be made solid or laminated. The armature winding can adopt a concentrated full pitch winding, a distributed short pitch winding, or an unconventional winding.

[0003] For example, the publication number is CN217769714U, and the Chinese authorized patent name is (An Efficient Permanent Magnet Direct Drive Transmission Device), which includes: a permanent magnet direct drive motor housing, a heat dissipation cover, and a motor rotating shaft.

Two symmetric first disassembly mechanisms are arranged inside the heat dissipation cover. The first disassembly mechanism includes a first limiting rod, and the first limiting rod penetrates through the heat dissipation cover and extends to the outside of the heat dissipation cover. Through the settings of the permanent magnet direct drive motor housing, the heat dissipation cover, the motor rotating shaft, the first disassembly mechanism, and the second disassembly mechanism, by pulling the first circular handle and pressing the second circular handle, the device can quickly install and disassemble the heat dissipation cover and the second circular handle, thereby facilitating the cleaning of dust on the heat dissipation cover and the fan blades, ensuring the heat dissipation effect of the permanent magnet direct drive motor, and avoiding damage to the permanent magnet direct drive motor caused by overheating.
