Description

At the same time, the corresponding manufacturing process solutions and requirements vary greatly, especially in the rotor core manufacturing and the motor stator and rotor assembly process.

[0003] The defects of the prior art are as follows:

[0004] 1. For interior permanent magnet motors, such as Figure 1 , Figure 2 As shown, since the permanent magnet is located inside the rotor, during the assembly of the stator and rotor, the rotor core protects the permanent magnet to a certain extent. However, when the stator and rotor are partially attracted and then continue to cage the rotor, it will cause quality risks of damage to the insulation and coil in the stator slot.

[0005] 2. For surface permanent magnet motors, such as Figure 3 , Figure 4 As shown, since the permanent magnets are usually tile-shaped and located on the outer surface of the rotor core, during the assembly of the stator and rotor, once the air gap causes partial attraction on one side, it will hinder the normal progress of the process and there will be quality risks of squeezing and damaging the permanent magnets.
