Title: Reluctance motor
Inventor: SAGAWA MASATO
IPC: H02K19/10
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase the power factor and efficiency, to reduce the size and to lower torque ripples and noise, by forming magnetic paths connecting magnetic poles in a magnetic body having a low coercive force. SOLUTION: Magnetic poles 'm' are formed at such places which divide a rotor R into four parts in the circumferential direction. Between each two adjacent magnetic poles 'm', magnetic baths oriented with respect to crystal c-axis are so formed as to annularly connect the magnetic poles. Therefore, the inner rotor R can be formed in a cylindrical shape as if having salient poles in the places where the magnetic pole 'm' are formed. As the inner rotor R is formed in a cylindrical shape and actually has no salient poles, the size can be reduced and a torque ripple can be held down to only a few and the generation of noise can be prevented. In other words, a section which has been a space in the conventional one is effectively used as a path for magnetic flux. Therefore, there is no necessity of forming excessive space in the motor, thereby reducing the size of the motor.
