[0002] Mining permanent magnet disk motors are a type of motor designed specifically for harsh environments such as mines. They typically feature a compact design to accommodate the tight spaces found in mines. Their structure primarily includes a stator, rotor, permanent magnets, bearings, and end caps. Permanent magnets are the core component of mining permanent magnet disk motors, and their performance directly impacts the motor's efficiency and reliability. Permanent magnets are typically made of high-performance rare earth permanent magnet materials, such as neodymium iron boron (NdFeB), which offer high magnetic energy product and coercive force, enabling them to maintain stable magnetic properties in harsh environments.

[0003] In addition, after the stamping and die-casting steps of the permanent magnet motor rotor, the rotor's central axis position needs to be roller-polished and corrected. After the rotor is die-cast, the staff needs to place the die-cast rotor center hole on specific equipment for inspection, which will take up a large area.

[0040] Example 2

[0041] The difference from the first embodiment is that, in order to realize the simultaneous execution of die casting and center hole detection, Figure 7-Figure 8 As shown, the detection component 4 includes a No. 2 motor 41, which is fixedly connected to the outer wall of the detection chamber 11. The output end of the No. 2 motor 41 is fixedly connected to the No. 2 rotating rod 42, which is in a retractable state.

During the rotation of the third gear 45, the protrusion block will be driven to rotate around it. When the protrusion block rotates, it will slide in the second arch hole 442 and drive the second connecting rod 44, the connecting column 43 and the second rotating rod 42 to slide together in the first fixed column 113. When the second rotating rod 42 slides to the inner side of the regular plate 115, the end of the second rotating rod 42 will pass through the center hole position of the rotor part and slide toward the direction of the second motor 41 again under the drive of the second motor 41. The second rotating rod 42 is rotated under the drive of the second motor 41, and the rotor part is rotated by the second rotating rod 42. The rotor part is rotated and detected, and whether it is tilted during the rotation process is observed in the external controller.
