During operation, the ellipticity of the magnetic field changes with the load, which has a particularly large impact on the performance and noise of the motor. Effective measures must be taken to suppress it. The most common current control method is to control the rotor skew, that is, evenly distributed array of skew slots are provided on the circumferential outer wall surface of the rotor core; the existing common groove type detection method is to measure with a vernier caliper, and measuring with a vernier caliper has relatively high requirements for the detector. Different people may measure different results due to inconsistent force, and the human factor is relatively large.

[0007] A lifting cylinder is fixedly connected to the upper part of the fixed base, and a connecting frame rotatably connected to the fixing member is fixedly connected to the output end of the lifting cylinder.

[0008] Further, a guide rod is fixedly connected to the upper part of the detection table body, and the connecting frame is slidably arranged on the guide rod.

Positioning pins 7 are provided on the upper part of the detection table body 2 and the lower part of the detection shaft rod 5, and the two groups of positioning pins 7 correspond up and down. A lifting cylinder 8 is fixedly connected to the upper part of the fixed base 1, and a connecting frame 9 that is rotatably connected to the fixing member 4 is fixedly connected to the output end of the lifting cylinder 8.

An installation plate 11 is fixedly connected to the upper part of the guide rod 10, and a contact induction module 12 that cooperates with the connecting frame 9 is fixedly connected to the installation plate 11.

[0023] It should be noted that the contact position between the contact induction module 12 and the connecting frame 9 is at the uppermost end of the lifting height of the fixing member 4, and contact induction control is carried out through this loading and unloading position.
