Abstract

In a reluctance type synchronous motor, a rotor has magnetic poles which have a low magnetic reluctance in an axial direction of the magnetic poles, and have a high magnetic reluctance toward a circumference of the rotor. The magnetic poles have less components orthogonal to axes thereof, so that armature reaction will be reduced.
