Embodiment 1

[0016] Such as figure 1 and figure 2 As shown, the radial magnetic circuit unipolar non-cogging reduction motor protector, the radial magnetic circuit unipolar non-cogging reduction motor protector includes a non-magnetic stainless steel sleeve 1, a permanent magnet 3 and two round Shaped magnetic stainless steel baffle 2;

[0017] The permanent magnet 3 is disc-shaped, and the permanent magnet 3 of the disc shape is fixedly installed in the non-magnetic stainless steel sleeve 1, and the magnetic circuit of the permanent magnet 3 of the disc shape is radially arranged, and the two circles Shaped magnetically conductive stainless steel baffle 2 is fixed on both ends of the non-magnetically conductive stainless steel sleeve 1, and the circular magnetically conductive stainless steel baffle 2 is attached to the two end faces of the disc-shaped permanent magnet 3, and the two circular guides The middle part of the magnetic stainless steel baffle plate 2 is respectively provide...

Embodiment 2

[0020] Such as figure 1 and figure 2 As shown, the radial magnetic circuit unipolar non-cogging reduction motor protector described in Embodiment 1, the inner peripheral surface of the shaft hole of the disc-shaped permanent magnet 3 and two circular magnetically conductive stainless steel baffles The gap between the inner peripheral surface of the shaft hole of 2 and the output shaft 4 of the motor 6 is 1 ~ 2mm. This not only ensures the normal operation of the motor 6, but also prevents iron filings and impurities from entering the motor body to the greatest extent.

[0021] Working principle: as Figure 1~Figure 3 As shown, the motor protector 7 of the present invention is installed coaxially with the motor 6 and the reducer 6 and is arranged between the motor 6 and the reducer 6 . Due to the effect of the disc-shaped permanent magnet 3, impurities such as iron filings are adsorbed on the surfaces of the circular magnetically conductive stainless steel baffle plate 2 a...

Abstract

The invention discloses a radial magnetic circuit monopole slotless decelerating type motor protector, and belongs to the technical field of motor protection equipment. The radial magnetic circuit monopole slotless decelerating type motor protector aims at solving the problems that a motor protector does not exist at present, therefore, the usage performance of a motor is reduced, the service life of the motor is shortened, and the maintenance cost of the motor is increased. A permanent magnet (3) is in the shape of a disc, the disc-shaped permanent magnet (3) is fixedly installed in a non-magnetism stainless steel sleeve (1), magnetic circuits of the disc-shaped permanent magnet (3) are arranged in the radial direction, two circular magnetic conductive stainless steel baffles (2) are fixed at the two ends in the non-magnetism stainless steel sleeve (1), and the circular magnetic conductive stainless steel baffles (2) are attached to the two end faces of the disc-shaped permanent magnet (3); the middles of the circular magnetic conductive stainless steel baffles (2) are each provided with a shaft hole, the middle of the disc-shaped permanent magnet (3) is also provided with a shaft hole, and the disc-shaped permanent magnet (3) and the shaft holes of the circular magnetic conductive stainless steel baffles (2) are coaxially arranged. The radial magnetic circuit monopole slotless decelerating type motor protector is used in a motor protection occasion.

Description

technical field [0001] The invention relates to a motor protector, which belongs to the technical field of motor protection equipment. Background technique [0002] The iron filings and other impurities produced by the friction of the reduction mechanism (such as the reducer) have an important impact on the long-term effective operation of the permanent magnet synchronous motor (hereinafter referred to as the motor). It will also have adverse effects, which will not only increase the maintenance cost of the motor, but also seriously affect the service life of the motor. Therefore, how to reduce impurities such as iron filings from entering the motor body, effectively improve the performance and life of the motor, and reduce the maintenance cost of the motor is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to provide a radial magnetic circuit unipolar non-cogging reduction motor protector to solve the ...
