Abstract

PURPOSE:To reduce irregularity in the rotation torque of a rotor with a simple construction by mutually shifting the positions of magnetic neutral points between field magnetic poles and auxiliary field magnetic poles. CONSTITUTION:Respective field magnetic poles 10 and auxiliary field magnetic poles 12 assume mechanical angles pi/2 and pi/4, the centers of the magnetic poles 12 forming N-poles correspond to the magnetic neutral points of the magnetic poles, as a result of which the magnetic neutral points between the magnetic poles 12 are mutually shifted. In the magnetic pole 10 as well as the magnetic pole 12, the interlinkage magnetic flux density with respect to an armature coil 16 due to the magnetic pole 10 and that due to the magnetic pole 12 become 2:1. Accordingly, in a period of 0<=theta<=pi/2, and pi<=theta<=3pi/2 of a period where the rotor 6 makes one revolution, the rotary torque is generated by the first phase armature coil 16, and in other periods, it is generated by the second phase armature coil 16. The combined torque is greatly reduced in its pulsating ratio as compared with the rotation torque due to the interlinkage magnetic flux from the magnetic flux 10. By these procedure, irregularity in the rotation torque can be reduced.
