Radial magnetic circuit monopole multistage slotless decelerating type motor protector

The invention discloses a radial magnetic circuit monopole multistage slotless decelerating type motor protector, and belongs to the technical field of motor protection equipment. The radial magnetic circuit monopole multistage 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 is in the shape of a disc, the disc-shaped permanent magnet is fixedly installed in a non-magnetism stainless steel sleeve, magnetic circuits of the disc-shaped permanent magnet are arranged in the radial direction, two circular magnetic conductive stainless steel baffles are fixed at the two ends in the non-magnetism stainless steel sleeve, and the circular magnetic conductive stainless steel baffles are attached to the two end faces of the disc-shaped permanent magnet; the middles of the circular magnetic conductive stainless steel baffles are each provided with a shaft hole, the middle of the disc-shaped permanent magnet is also provided with a shaft hole, the shaft hole of the disc-shaped permanent magnet and the shaft holes of the circular magnetic conductive stainless steel baffles are coaxially arranged, and multiple radial magnetic circuit monopole multistage slotless decelerating type motor protector bodies are coaxially arranged. The radial magnetic circuit monopole multistage slotless decelerating type motor protector is used in a bigger space occasion for protecting the motor.
