They can reduce motor weight and volume, reduce winding resistance, improve motor efficiency and power density, and save costs; there is no crossover between windings, and there will be no phase-to-phase insulation failure, which improves motor reliability.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the embodiment, Figure 1-4 A test platform for permanent magnet motor processing is provided, comprising a high workbench 1, the top of the high workbench 1 is detachably connected to a permanent magnet motor body 2 by bolts, the right end of the high workbench 1 is fixedly connected to a low work frame 3, a lifting assembly 4 is arranged on the low work frame 3, a lateral movement assembly 5 is arranged on the lifting assembly 4, and a test assembly 6 for testing the permanent magnet motor body 2 is arranged on the top of the lateral movement assembly 5;

[0025] Through the above settings, firstly, the permanent magnet motor body 2 is installed on the high workbench 1 by bolts, the cylinder 41 is started, and the cylinder push rod 42 is pushed out to make the mounting base plate 43 move vertically upward until it moves to the test assembly 6 and the output end of the permanent magnet motor body 2. In this process, the four guide columns 44 play a guiding role to ensure that the mounting base plate 43 keeps moving vertically upward, and the bearing is connected to the outer side of the output end of the permanent magnet motor body 2. The hand wheel 57 is turned, and the threaded rod 56 rotates, and the threaded sleeve 58 moves to the left or right along the center line of the threaded rod 56.
