Rotor magnets fixing structure

Abstract

A rotor magnets fixing structure includes a magnetizable main body consisting of laminated silicon steel sheets; multiple magnets fitly contacting with a circumferential surface of the magnetizable main body; and two end surface silicon steel sheets disposed on upper and lower ends of the magnetizable main body. The magnets are provided on respect upper and lower ends with a recess, and the end surface silicon steel sheets are provided on respective outer periphery with fixing lugs for covering the upper and lower ends of the magnets. The fixing lugs are formed with a retaining hook to interfere and engage with the recesses on the magnets. Therefore, the rotor can be manufactured with less cost and precision, while a frictional force between the retaining hooks and the recesses is increased to ensure stable magnet fixation and avoid damage and malfunction of the rotor and parts thereof.
