Abstract

The invention discloses a novel motor rotor structure. The novel motor rotor structure comprises rotor punching pieces, magnetic steel, rotor magnetic steel pressure plates, fastening bolts and a locking mechanism, wherein the locking mechanism comprises aluminum-casting end rings and mouse cage strips which are integrally formed, each aluminum-casting end ring is a round ring, and movable balancing holes are formed in the round ring; the magnetic steel is mounted on outer arc surfaces of the rotor punching pieces, the rotor magnetic steel pressure plates are respectively arranged on two sidesof the rotor punching pieces, and one aluminum-casting end ring is arranged on the inner side of each rotor magnetic steel pressure plate; a plurality of bolt holes and a plurality of mouse cage holes are formed in the rotor magnetic steel pressure plates and the rotor punching pieces; the fastening bolts penetrate through the rotor magnetic steel pressure plates and the rotor punching pieces andare used for locking the rotor magnetic steel pressure plates and preventing the axial movement of the magnetic steel; and the mouse cage strips and the aluminum-casting end rings are connected withthe rotor punching pieces through interference fit. According to the novel motor rotor structure, the problems that silicon steel sheets are staggered and moved in the carrying and transportation processes can be solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a novel motor rotor structure, which is mainly suitable for speed-regulating permanent magnet synchronous motors. Background technique [0002] Since most of the motor rotors used in compressors do not have shafts during transportation, the rotor silicon steel sheets must be axially fixed after lamination. In the prior art, the rotor of the speed-regulating permanent magnet synchronous motor is generally locked axially by bolts, but the bolt holes and bolt tolerances must be properly matched, neither too tight nor too loose; Silicon steel sheets with large gaps are easy to dislocate and move. Moreover, in the process of handling and transportation, the slight collision of the rotor may also easily cause the dislocation and movement of the silicon steel sheet. [0003] The harm caused by dislocation movement is as follows: [0004] 1. Changes in the inner diameter and outer diam...
