ABSTRACT:
An electric-machine rotor is composed of a field coil, a pair of pole cores having a plurality of claw poles to enclose the field coil, a plurality of auxiliary permanent magnets disposed between the claw poles, a shaft fixed to the pair of pole cores, and a pair of slip rings connected to the field coil. The rotor is provided with a pattern on a surface of the pole cores for indicating the polarity of the claw poles when the field coil is energized.
