Abstract

The invention discloses a magnetic pole protective layer flexible molding process and system; the process comprises: fitting magnet steel to corresponding position of one side wall of a magnet yoke, applying reinforcing material and a vacuum bag sequentially to the sidewall of the magnet steel and magnet yoke, such that the vacuum bag, along with the sidewall of the magnet steel and magnet yoke, forms a closed system; impregnating, to be specific, evacuating the closed system to inject an impregnating liquid to the closed system to implement wetting and impregnating; heating and / or transmitting ultrasonic to the closed system during impregnating; after impregnating, carrying out curing, to be specific curing the impregnating liquid to form a protective layer. By heating, it is possible to reduce the angle of contact; by ultrasonic vibration, mechanical wave is transmitted to the impregnating liquid; both facilitates full wetting and impregnating of the impregnating liquid; therefore, holes in the formed protective layer are decreased.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a flexible molding process and molding system for a magnetic pole protection layer. Background technique [0002] Please refer to Figure 1-1~1-2 , Picture 1-1 It is a schematic diagram of the permanent magnet motor magnetic pole protection layer forming system; Figure 1-2 for Picture 1-1 Schematic diagram of the details of the middle magnetic steel. [0003] In FIG. 1 , the magnetic steel 16 is arranged on the inner wall of the magnetic yoke 15 of the outer rotor, pressed against the magnetic yoke 15 by beading, and fastened by bolts. In addition, the protective layer 142 is formed by injecting glue on the surface of the magnetic steel 16 . The specific process is: [0004] At first, cover reinforcing material 142 (such as glass fiber cloth), release cloth 143, guide net 141 in this way on the surface of magnetic steel 16, then use light, flexible vacuum bag 17 to seal and...
