Abstract
A motor according to the present invention is a motor using a rotor including two first rotator portions , each having a permanent magnet , and a second rotator portion having magnetic saliency inserted therebetween, coupled in a direction of a rotating shaft , and part of the rotor is replaced with a reluctance motor, whereby an amount of the permanent magnet is reduced, thus making it possible to reduce generated voltage. Further, there are provided the first rotator portion on both sides of the second rotator portion , whereby the second rotator portion is magnetically saturated through the effective use of going-round of magnetic flux to raise salient ratio. Thus, reluctance torque caused in the second rotator portion is increased, whereby it is possible to increase torque as a whole and to obtain a high-output motor.
