Method and assembling device for assembling and disassembling stator and rotor of permanent magnet synchronous motor

Abstract

The invention provides a method and assembling device for assembling and disassembling a stator and a rotor of a permanent magnet synchronous motor. The method is characterized by adopting a rocker arm vertical permanent magnet synchronous motor stator and rotor assembling and disassembling method to fix a rotor on a rocker arm by a floating positioning seat, with the excircle and end face at the shaft extension end or the excircle and end face at the extension end of the rotor as the positioning surfaces, plugging a tapered positioning pin after the floating positioning seat is fixedly positioned, ensuring the axis of the rotor to be vertical to the horizontal plane and on the same straight line with the center line of a stator and arranging a pilot rod at the front end of the rotor; fixing the stator on a stator positioning disc by a bolt, with a bearing chamber at the end where the end cover is assembled and the end face of the bearing chamber as the positioning surfaces; installing the stator positioning disc on which the stator is installed in the center of a stator fixing station and ensuring the central axis of the stator to be vertical to the horizontal plane and coaxial with the floating positioning seat of the rotor; installing the rocker arm on a column, driving the rocker arm to move up and down via a screw drive mechanism and driving the rotor installed on the rocker arm to move up and down together when the rocker arm moves up and down to realize assembly and disassembly of the stator and the rotor of the permanent magnet synchronous motor.

Description

Permanent magnet synchronous motor stator and rotor assembly and disassembly method and assembly device technical field The invention relates to an assembly method and device of motor components, in particular to a vertical assembly of a large-power permanent magnet synchronous motor stator and rotor to overcome the magnetic field attraction of a permanent magnet and ensure controllable assembly speed and position of the stator and rotor assembly The method and device, especially when the stator and rotor of the permanent magnet synchronous motor with a larger power of 30KW or more are vertically or horizontally assembled or disassembled, the attraction force cannot be controlled manually. Background technique With the development of motor control technology, AC asynchronous motors are widely used because of their simple structure, reliable operation, long life, low cost and easy maintenance. However, compared with DC motors, it has poor speed regulation performance, small...

Problems solved by technology

The purpose of the present invention is to aim at the attraction of the existing permanent magnet synchronous motor when the stator and rotor are combined and disassembled, which will cause the relative movement speed of the stator and rotor during the disassembly and assembly process of the permanent magnet synchronous motor to be uncontrollable and unsafe for workers to operate. At the same time, the production efficiency and The problem of product quality is also difficult to guarantee. A permanent magnet synchronous motor is proposed. When the permanent magnet synchronous motor is assembled, the permanent magnet synchronous motor is dismantled and assembled.
