Abstract

The invention relates to a fixing structure of a permanent magnet generator or a motor permanent magnet. The fixing structure comprises a rotor cylinder and permanent magnets, wherein the permanent magnets are arranged along the circumference of the surface of the rotor cylinder at intervals. Pole shoes are arranged among the permanent magnets along the circumference of the surface of the rotor cylinder and are used for fixing the permanent magnets, and a protruding part for clamping tightly the permanent magnets on two sides is respectively arranged on two side surfaces of each pole shoe. Each permanent magnet is fixed on the surface of the rotor cylinder by virtue of adjacent pole shoes on the two sides of each permanent magnet. According to the invention, the problem that the fixation of a current generator permanent magnet is not firm and consumes time and labors is effectively solved, the air gaps between the rotor and the stator can be reduced and the working efficiency of the generator is improved.

Description

technical field [0001] The invention relates to a generator or a motor, in particular to a permanent magnet fixing structure of a permanent magnet generator or a motor. Background technique [0002] Permanent magnet generators are widely used in various power generation fields. In the existing permanent magnet generators, the permanent magnets are mostly fixed on the surface of the rotor cylinder structure (the permanent magnets are in the air gap). In order to fix the permanent magnets, glue is generally used to bond them to the surface of the rotor. Each permanent magnet must be pressed to the surface of the rotor until the bonding is firm. Large machines require hundreds of permanent magnets. The entire bonding and fixing process It is very time-consuming, and there is a problem of poor bonding. Although some brackets are used to help fix the permanent magnets, once there is a problem with the glue, the brackets cannot fix the permanent magnets, and the permanent magnets...
