Permanent magnet motor pole protection coating forming process and processing equipment

Abstract

The invention discloses a permanent magnet motor pole protection coating forming process and auxiliary processing equipment. In the permanent magnet motor pole protection coating forming process, a motor rotor is horizontally placed, positions of an inlet and an outlet operating on a vacuum bag at the current state are controlled to only aligned to an arc section at the bottom part of the motor rotor to perform vacuum pumping and inject an adhesive, the motor rotor is driven to rotate by a predetermined angle after the adhesive of the arc section is preliminarily solidified so as to enable an arc section in which the adhesive is not injected to rotate to the bottom part until all arc sections in the circumferential direction of the motor rotor complete injection of the adhesive. Therefore, a gap between magnetic steel and the magnet yoke wall is dipped in the adhesive of a reinforcing material and simultaneously subjected to a gravity action, a radial pressure gradient action and an axial pressure gradient action, and adhesive filling for the gap between the magnetic steel and the magnet yoke wall and a gap between the magnetic steel and a magnetic steel layer is guaranteed. In addition, a medium used for transferring heat of the running process is arranged between the magnetic steel and the magnet yoke wall, so that the temperature of the magnetic steel can be suppressed, and the performance and the magnetic steel is not damaged by temperature rising and corrosion.
