Problems solved by technology

[0002] Usually, the rotor of a motor contains an iron core and a shaft, while the rotor of a permanent magnet motor also contains a magnetic steel. Orientation, some process the outer surface of the iron core into the form of dovetail grooves, which is complicated to process. If wire cutting is used, the processing cost is high and time-consuming. Some adopt the method of processing rows of holes on the outer surface of the iron core by positioning pins Or screw positioning, which is also time-consuming, and the process is cumbersome, which is not only labor-intensive and time-consuming, but also increases processing costs

Abstract

The invention discloses a rotor structure of a permanent magnet motor. The rotor structure comprises a shaft, a rotor core, retaining rings, baffle rings and magnetic steel, wherein a plurality of grooves are formed in the whole periphery of the outer-circle surface of the rotor core, and the baffle rings are arranged in the grooves. The rotor structure has the advantages that the rotor core can be easily and conveniently machined just by a common lathe, production efficiency is high, positioning is easy and convenient due to the adoption of the baffle rings in the magnetic steel bonding process, the structure is simple, and the machining and manufacturing process is convenient to carry out.

Description

technical field [0001] The invention relates to a rotor structure of a motor, in particular to a rotor structure of a permanent magnet motor. Background technique [0002] Usually, the rotor of a motor contains an iron core and a shaft, while the rotor of a permanent magnet motor also contains a magnetic steel. Orientation, some process the outer surface of the iron core into the form of dovetail grooves, which is complicated to process. If wire cutting is used, the processing cost is high and time-consuming. Some adopt the method of processing rows of holes on the outer surface of the iron core by positioning pins Positioning by means of screws or screws is also time-consuming, and the process is cumbersome, which not only takes time and labor, but also increases processing costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a permanent magnet motor rotor structure. [0004] The technical solution adopt...
