Title: Rotor for synchronous motor
Inventor: NASHIKI MASAYUKI
IPC: H02K1/24
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous motor excellent in performance by realizing a rotor structure where respective magnetic paths are separated magnetically. SOLUTION: A plurality of subdivided magnetic paths 15-18, 47 made of a high permeability material conducting magnetically between rotor poles and laminated in the direction of a rotary shaft having a high magnetic reluctance are integrated, through welding, with nonmagnetic coupling members 19-21, 48 made of a nonmagnetic material, e.g. stainless steel, thus forming a rotor. A coupling part passing flux easily is eliminated between magnetic paths in the circumferential direction thus realizing a rotor structure where respective magnetic paths are separated magnetically and the difference of reluctance can be increased between poles. According to the structure, torque generation is prevented from decreasing due to leakage flux and a synchronous motor excellent in performance is realized.
