[0032] Since the rotor 62 is ejected from the stator 61 in the vertical direction, the ejection position of the stator 61 can be controlled, and then other mechanisms are not needed to support the ejected rotor 62, the rotor 62 can be taken out of the stator 61 when the rotor 62 is ejected to the appropriate position, which is very convenient to use, greatly shortens the disassembly time of the motor, and improves the efficiency of maintenance.

[0033] The new energy automobile motor stator rotor separation device has few parts and simple structure, so the cost is low, and the operation is simple and convenient to use.

[0034] In order to improve the versatility, more types and specifications of motors can be adapted, and the fixed waist hole 11 is arranged in an annular array along the axis of the ejection hole 12. The annular array of the fixed waist hole 11 can adapt to a variety of motors.

[0035] The waist-shaped fixed waist hole 11 can also be arranged along the radial direction of the ejection hole 12, that is, the length direction of the fixed waist hole 11 is arranged along the radial direction of the ejection hole 12, and then different diameter motors can be used.
