Abstract

The invention discloses a flexible molding process and a forming system for a magnetic pole protection layer. The forming process is carried out by: assembling a magnetic steel at a corresponding position on one side wall of a magnetic yoke, laying reinforcement materials, the vacuum bag on the magnetic steel and the magnetic steel in sequence. One side wall surface of the magnetic yoke, the vacuum bag forms a closed system with the magnetic steel and the one side wall surface of the magnetic yoke; impregnation process: vacuumize the closed system so that the impregnating liquid is injected into the closed system In the system, wetting and impregnation are realized; during the impregnation process, the closed system is heated and / or ultrasonic waves are emitted at the same time; after the impregnation process, a curing process is performed, and the impregnation liquid is cured to form a protective layer. Heating can reduce the contact angle, and ultrasonic vibration transmits mechanical waves to the impregnating liquid, both of which are conducive to the infiltration and full impregnation of the impregnating liquid, thereby reducing the voids in the formed protective layer.

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...
