specific Embodiment approach

[0200] In this paper, the four horizontal cantilevers are respectively defined as the first horizontal cantilever 90221, the second horizontal cantilever 90222, the third horizontal cantilever 90223 and the fourth horizontal cantilever 90224. The 12 o'clock direction and the 3 o'clock direction, that is, the horizontal cantilever module 9022 and the distance measuring sensor 907 are axially arranged one by one.

[0201] please refer again Figure 19 , in a specific implementation manner, there is a group of ranging sensors on the same axis, and a group of ranging sensors includes at least two ranging sensors 907, Figure 19 2 shows a specific embodiment in which a group of distance measuring sensors includes two, and the distance measuring sensors 907 in the same group are arranged at intervals along the same axial direction, and the positions can be arbitrary. This article continues to introduce the technical solution by taking the two ranging sensors 907 in the same group r...

Abstract

The invention discloses a permanent magnet motor pole protection coating forming process and auxiliary processing equipment. In the permanent magnet motor pole protection coating forming process, a motor rotor is horizontally placed, positions of an inlet and an outlet operating on a vacuum bag at the current state are controlled to only aligned to an arc section at the bottom part of the motor rotor to perform vacuum pumping and inject an adhesive, the motor rotor is driven to rotate by a predetermined angle after the adhesive of the arc section is preliminarily solidified so as to enable an arc section in which the adhesive is not injected to rotate to the bottom part until all arc sections in the circumferential direction of the motor rotor complete injection of the adhesive. Therefore, a gap between magnetic steel and the magnet yoke wall is dipped in the adhesive of a reinforcing material and simultaneously subjected to a gravity action, a radial pressure gradient action and an axial pressure gradient action, and adhesive filling for the gap between the magnetic steel and the magnet yoke wall and a gap between the magnetic steel and a magnetic steel layer is guaranteed. In addition, a medium used for transferring heat of the running process is arranged between the magnetic steel and the magnet yoke wall, so that the temperature of the magnetic steel can be suppressed, and the performance and the magnetic steel is not damaged by temperature rising and corrosion.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a forming process and process equipment for a magnetic pole protection coating of a permanent magnet motor. Background technique [0002] Permanent magnet motor is an electromagnetic device that converts mechanical energy and electrical energy through the medium of magnetic field.
