Title:

VACUUM ASSISTED RESIN INFUSION PROTECTION COATING, SYSTEM AND METHOD FOR PERMANENT MAGNET MOTOR ROTOR

Document Type and Number:

WIPO Patent Application WO/2016/029769

Kind Code:

A1

Abstract:

Provided are a vacuum assisted resin infusion protection coating, system and method for a permanent magnet motor rotor. The vacuum assisted resin infusion protection coating comprises a reinforcing phase, demoulding cloth, and a flow guide net which are laid on the surface of a magnetic pole of a rotor in sequence, wherein an end part of a resin infusion pipeline and an end part of an air suction pipe are respectively fixed on the exterior of the flow guide net, the rotor is hermetically connected to a vacuum isolation film, and the vacuum isolation film covers the reinforcing phase, the demoulding cloth, the flow guide net, the end part of the resin infusion pipeline, and the end part of the air suction pipe. In the present invention, vacuum assisted resin infusion and moulding equipment is applied to the magnetic pole protection of a permanent magnet motor rotor so as to form a resin coating on the surface of the magnetic pole of the permanent magnet motor rotor, and the thickness of the resin coating on the surface of the magnetic pole is easily controlled, and mould sleeve tools are not required. The vacuum assisted resin infusion protection system and method can achieve a good casting effect, and thus the mechanical performance and anticorrosion grade of rotor magnetic poles can be enhanced.
