Axial magnetic circuit monopole multistage tooth-space-omitted deceleration type motor protector

The invention discloses an axial magnetic circuit monopole multistage tooth-space-omitted deceleration type motor protector, belongs to the technical field of motor protection equipment, and aims at solving the existing problems that the using performance and service life of a motor are reduced, and the maintenance cost of the motor is increased owing to the lack of the motor protector. In each of axial magnetic circuit monopole tooth-space-omitted deceleration type motor protectors, a permanent magnet is of a disc shape, the disc-shaped permanent magnet is fixedly mounted in a nonmagnetic stainless steel sleeve, a magnetic circuit of the disc-shaped permanent magnet is arranged in the axial direction, two circular magnetic stainless steel baffles are fixed to the two ends in the nonmagnetic stainless steel sleeve, the two circular magnetic stainless steel baffles are attached to the two end faces of the disc-shaped permanent magnet, axle holes are formed in the middle of the two circular magnetic stainless steel baffles respectively, an axle hole is also formed in the middle of the disc-shaped permanent magnet, the axle hole of the disc-shaped permanent magnet and the axle holes of the two circular magnetic stainless steel baffles are coaxially arranged; the multiple axial magnetic circuit monopole tooth-space-omitted deceleration type motor protectors are coaxially arranged. The axial magnetic circuit monopole multistage tooth-space-omitted deceleration type motor protector is applied to large space occasions for protecting the motor.
