Hollow shaft motor arc magnetic steel positioning and fixing structure

Abstract

The utility model discloses a hollow shaft motor arc magnetic steel positioning and fixed structure, it includes hollow shaft, a plurality of arc magnetic steel and the magnetic steel positioning ring of spacing set in the hollow shaft, the magnetic steel positioning ring includes first limit ring and second limit ring of spacing distribution before and after to and the multiple partition board of corresponding arc magnetic steel quantity of circumferential array setting between first limit ring and second limit ring, one end of partition board is connected on first limit ring outside wall and is connected on second limit ring front end face another end, the positioning groove of adapting arc magnetic steel edge shape is set up in the both sides of partition board, and every arc magnetic steel is limited and is connected in the positioning groove between adjacent two partition boards and is close to hollow shaft and second limit ring, the utility model discloses on the basis that guarantees that magnetic steel does not fall, can reduce the processing difficulty of hollow shaft to the greatest extent, reduces processing procedure, reduces cost.
