Flux-concentrating rotor structure

Abstract

A flux-concentrating rotor structure is disclosed and includes an iron core and plural magnet components. The iron core is formed by stacking plural silicon steel sheets and includes plural magnet-receiving slots arranged along a circumferential direction. Each magnet-receiving slot has a T-shaped section. Each two adjacent magnet-receiving slots have a radial bridge, whereby each silicon steel sheet is integrally formed. The magnet components are arranged in the iron core, and correspondingly received within the magnet-receiving slots. Each magnet component includes two radial magnets and one tangential magnet. The two radial magnets are located on both sides of the tangential magnet along the circumferential direction and in contact with the tangential magnet. The two radial magnets are magnetized along the radial direction respectively and have opposite magnetizing directions. The tangential magnet is magnetized along the tangential direction. The tangential magnets in two adjacent magnet components have opposite magnetizing directions.
