Description

TECHNICAL FIELD

[0001] The utility model discloses a stator press-fitting technical field, and specifically is motor stator assembly press-fitting tool. BACKGROUND

[0002] The stator assembly press-fitting tool is a special tool for press-fitting operation of a stator assembly. When the motor stator is assembled, a clamping tool is used to effectively assemble and form the motor housing, realizing the assembly and formation of the motor. The stator in the motor provides a magnetic field for the rotor, and therefore the quality of the stator installation directly affects the use quality of the motor.
