Vacuum-assisted resin filling system and method of permanent magnet motor rotor

Abstract

The invention provides a vacuum-assistant resin filling system and method of a permanent magnet motor rotor. The a vacuum-assisted resin filling protecting covering layer of the permanent magnet motorrotor comprises a reinforcing phase, a die releasing cloth and a flow guide net which are sequentially paved on the magnetic pole surface of the rotor, wherein the end part of a glue injection pipeline and the end part of an air exhausting pipe are correspondingly fixed to the outside of the flow guide net; a vacuum isolating film is in sealing connection with the rotor and covers the reinforcingphase, the die releasing cloth, the flow guide net, the end part of the glue injection pipeline and the end part of the air exhausting pipe. A vacuum-assisted resin filling forming technology deviceis applied to magnetic pole protection of the permanent magnet motor rotor; a resin covering layer can be formed on the magnetic pole surface of the permanent magnet motor rotor; and the thickness ofthe resin covering layer on the magnetic pole surface is easily controlled, and a die sleeve workpiece is not required. With the adoption of the vacuum-assisted resin filling and system, good fillingeffect can be realized; the magnetic performance of a magnetic pole of the rotor can be improved; and the corrosion grade can be increased.

Description

[0001] This application is a divisional application with an application date of August 27, 2014, an application number of 201410428379.6, and an invention title of "Vacuum-assisted resin infusion protective coating, system and method for permanent magnet motor rotors". technical field [0002] The invention relates to a resin infusion protective coating, a system and a method, in particular to a vacuum-assisted resin infusion system and method for a rotor of a permanent magnet motor. Background technique [0003] The pole protection of permanent magnet motors and permanent magnet generators is crucial to their safe operation, especially wind turbines. In recent years, with the rapid development of the wind power industry, wind turbines have gradually become larger, the requirements for mechanical strength have become higher and higher, and the operating environment has become more and more harsh. The normal operation and service life of generators bring challenges, especiall...

Problems solved by technology

[0007] At the same time, especially for permanent magnet wind turbine rotors, the surface structure that needs to be covered by resin coating is complex, the surface of magnetic poles and rotor yoke is uneven, there are many gaps and pores, and it is difficult to fully rely on existing technologies. Filling these pores cannot provide good anti-corrosion protection for the rotor poles. Therefore, how to achieve a resin coating with better performance is another technical problem that needs to be solved
