Abstract

The invention provides a permanent magnet motor rotor mounting system and mounting method. The mounting system comprises a workbench, a motor stator, two adjusting supports and two connecting rods, wherein the motor stator, the two adjusting supports and the two connecting rods are located on the workbench. The mounting method comprises the steps: S1, arranging the motor stator between the two adjusting supports; S2, two connecting rods respectively penetrating through the two through holes, one connecting rod penetrating through the stator mounting cavity, and two ends of the permanent magnetrotor being respectively connected with one connecting rod; S3, the controller adjusting the position of the permanent magnet rotor according to the data sensed by the position sensor, so that the center line of the permanent magnet rotor coincides with the center line of the stator mounting cavity; S4, the connecting rod driving the permanent magnet rotor to move along the center line of the permanent magnet rotor; and S5, after the permanent magnet rotor moves to a set position, stopping the propulsion driving equipment, and completing installation. The distance between the exterior of thepermanent magnet rotor and the inner wall of the stator mounting cavity is accurately controlled, and damage caused by collision between the permanent magnet rotor and the motor stator is prevented.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motor rotor installation, in particular to a permanent magnet motor rotor installation system and an installation method. Background technique [0002] Permanent magnet motors have the advantages of high efficiency, high power density, small size, and light weight. The rotor speed of the high-speed permanent magnet motor is high, and the permanent magnet attached to the rotor surface needs to bear the huge centrifugal force. In order to prevent the permanent magnet from detaching, sliding, damage, etc., the surface of the permanent magnet needs to be covered with a certain thickness of sheath. However, this further narrows the gap between the already small stator and the rotor of the high-speed permanent magnet motor, causing the rotor to easily rub against the stator when it is installed into the stator, causing damage to the permanent magnet motor components.
