[0002] The rotor and stator of the shielded motor are all wrapped with shielding sleeves, with a gap of 0.5-1.0mm between them. The upper and lower ends of the stator shielding sleeve are welding joints. Due to the process precision, there are slight deformations at the welding points of the rotor shielding sleeve. Since the gap between the rotor and stator shielding sleeves is very small, there is friction between the rotor shielding sleeve and the stator shielding sleeve due to welding deformation, which affects the service life of the shielded motor. The motor shielding sleeve needs to be deformed.
