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

The invention discloses an axial magnetic circuit monopole 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. A permanent magnet (3) is of a disc shape; the disc-shaped permanent magnet (3) is fixedly mounted in a nonmagnetic stainless steel sleeve (1); a magnetic circuit of the disc-shaped permanent magnet (3) is arranged in the axial direction; two circular magnetic stainless steel baffles (2) are fixed to the two ends in a nonmagnetic stainless steel sleeve (1); the circular magnetic stainless steel baffles (2) are attached to the two end faces of the disc-shaped permanent magnet (3); axle holes are formed in the middle of the two circular magnetic stainless steel baffles (2) respectively; an axle hole is also formed in the middle of the disc-shaped permanent magnet (3); the axle hole of the disc-shaped permanent magnet (3) and the axle holes of the two circular magnetic stainless steel baffles (2) are coaxially arranged. The axial magnetic circuit monopole tooth-space-omitted deceleration type motor protector is applied to motor protection occasions.
