Description

Technical Field

[0002] During the assembly process of the engine and motor, it is generally necessary to install the motor rotor and the motor stator in sequence, and the relative installation position of the motor stator and the motor rotor needs to be ensured, that is, a certain air gap needs to be reserved between the motor rotor and the motor stator. When the engine crankshaft oil seal, motor, etc. fail, the motor needs to be disassembled for maintenance.

[0003] During the assembly of the motor stator and the motor rotor, since the permanent magnets on the motor rotor or the motor stator have strong magnetism, there is magnetic force between the motor stator and the motor rotor and the gap between them is only 1mm. Therefore, in the process of the motor rotor and the motor stator approaching each other, large-scale tooling equipment is required to prevent the magnets and the iron core from being attracted to each other and colliding violently, and to prevent the motor rotor from having difficulty entering the inner cavity of the motor stator and easily damaging the magnets and enameled wire.
