A ROTATING ELECTRIC MACHINE ABSTRACT OF THE DISCLOSURE An Electric rotating machine comprises a field per- manent magnet which is permanently magnetized to N and S poles alternately and an armature core which is arranged coaxially with the magnet and has a plurality of salient poles faced to the magnet. Poly-phase coils are wound on the root of the sa- lient poles. According to arranging an indented portion at the major face of the salient pole facing to the magnet, a cogging torque can be remarkably reduced, and further by ar- ranging auxiliary salient poles ripple torque can be also re- duced. - 0 - 0 -
