Patent ID: 11254071

Abstract:
A flexible molding process and system for a magnetic pole protective layer. The molding process is as follows: assembling magnet steels at respective positions on a side wall surface of a magnetic yoke, laying a reinforcing material and a vacuum bag in the listed sequence on the magnet steel and the side wall surface of the magnetic yoke, wherein the vacuum bag, the magnet steels and the side wall surface of the magnetic yoke form a sealed system; performing an impregnation process, including vacuumizing the sealed system to allow the impregnation liquid to be injected into the sealed system, to achieve infiltration and impregnation; heating the sealed system and/or emitting ultrasonic waves to the sealed system while performing the impregnation process; and performing a curing process after the impregnation process, wherein the impregnation liquid and the reinforcing material are cured to form a protective layer.
