Title:
HIGH-EFFICIENCY FERRITE MAGNETISM-GATHERING SYNCHRONOUS MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/038112
Kind Code:
A1
Abstract:
Provided by the present invention is a high-efficiency ferrite magnetism-gathering synchronous motor, comprising a stator component, a rotor component, a housing, a front cover and a rear cover, wherein the stator component comprises a stator core and an armature winding embedded in a slot of the stator core; the rotor component comprises a main shaft, a rotor, a front baffle and a back baffle; the rotor comprises a rotor magnetizer, a tangential magnetized ferrite magnetic steel and a connection base, the connection base being fixedly sleeved on the main shaft; the rotor magnetizer is clamped on circumferential surface of the connection base with a gap therebetween, and the tangential magnetized ferrite magnetic steel is fixedly clamped between adjacent rotor magnetizers; the front and rear baffles are respectively mounted at both ends of the connection base and are used to tightly fix the rotor magnetizer and the tangential magnetized ferrite magnetic steel to the circumferential surface of the connection base; the stator and the rotor components are mounted in the housing, and the front and rear covers are respectively mounted at both ends of the housing and are mounted on the main shaft by means of bearings. The magnetic length of the rotor is longer than the stack thickness of the stator core. The stator and rotor of the motor may achieve an air-gap magnetic density of more than 1.0 tesla, are low cost and have a high efficiency.
