Stepper and servo motors can be disassembled for maintenance or modification, but it is best to let the manufacturer do it, because it is difficult to install back to the original without professional equipment after disassembly, and may cause the following problems:
1. The quartz sheet in the code disc is easy to break, and after entering the dust, the life and accuracy will not be guaranteed.
2. The gap between the motor and stator cannot be guaranteed.
3. The performance of the magnetic steel material is destroyed, and even causes magnetic loss, and the motor torque is greatly reduced.
