Abstract

The invention provides an I-shaped magnetic steel T-shaped pin locking structure of a permanent magnet motor, which belongs to the technical field of permanent magnet motors. Grooves are formed in themiddle positions of the two sides of a permanent magnet; the T-shaped part of the T-shaped pin is inserted into the grooves of the two permanent magnets which are arranged in parallel; the lower partof the T-shaped pin faces the surface of the rotor; screws fix the T-shaped pins and the surface of the rotor; the baffle plate is inserted into the grooves of the two permanent magnets which are arranged in parallel; the baffle plate is located above the T-shaped part of the T-shaped pin, the lower surface of the baffle plate abuts against the upper surface of the T-shaped part of the T-shaped pin to prevent screws from falling off, the baffle plate is longer than the permanent magnet, a baffle plate clamping groove is formed in the magnetic pole pressing plate, the baffle plate clamping groove is matched with the baffle plate in shape, and the part, longer than the permanent magnet, of the baffle plate is inserted into the baffle plate clamping groove, and the magnetic pole pressing plate fixes the baffle plate. The structure provided in the invention is used for the surface-mounted magnetic steel permanent magnet motor, and an I-shaped magnetic steel T-shaped pin locking structureis adopted, so that the reliability of the surface-mounted magnetic steel structure can be greatly improved, and the process difficulty and the cost are reduced.

Description

technical field [0001] The invention relates to a permanent magnet motor I-shaped magnetic steel T-shaped pin locking structure, which belongs to the technical field of permanent magnet motors. Background technique [0002] A permanent magnet motor consists of a stator, a rotor, and an end cover. The stator is basically the same as the ordinary induction motor, and adopts a lamination structure to reduce the iron loss when the motor is running. The rotor can be made solid or stacked with laminations. The armature winding can be concentrated full-pitch winding, or distributed short-pitch winding and unconventional winding. [0003] In the prior art, the surface-mounted magnetic steel process schemes of permanent magnet motors are divided into the following types: [0004] 1. Dovetail groove structure, the dovetail groove structure is used for punching sheet; however, it is difficult to control the magnetic flux leakage of magnetic steel in this method, and the depth of the...
