[0002] Multiple permanent magnet poles are needed in permanent magnet motors. During the assembly process of permanent magnet motors, a large number of permanent magnet poles are bulked together, which takes up a lot of space and is prone to safety accidents. That is, when multiple permanent magnet poles need to be stacked together, the repulsive force generated between the permanent magnet poles makes stacking difficult. At the same time, since the top and bottom surfaces of the permanent magnet poles have a certain curvature in their structure, it is very inconvenient to fix the permanent magnet poles and it is easy to damage the permanent magnet poles.

[0003] In the specification of a stacking device and stacking method for permanent magnet motor rotor poles in the prior art (publication number CN115765343A), it is mentioned that "clamps are also provided on both sides of the base plate, and the base plate, the baffle and the clamps constitute a positioning groove. A process pressure plate for pressing the rotor pole is also provided on the positioning groove, and the distance between the two clamps matches the length of the rotor pole, so that when the process pressure plate presses the rotor pole, the rotor pole only contacts the clamps". However, the assembly structure in the prior art cannot stabilize the rotor, resulting in the inability to align the loaded poles in time when entering the rotor, and it is easy to be misaligned, and the assembly is not stable, accurate and fast.
