ELECTRIC ROTATING MACHINE

摘要

In an electric rotating machine, a stator has an armature coil wound around an armature core segments with M pairs of poles, and N pairs of field sources (field coil and field magnetic field), a rotor has K soft magnetic members including a plurality of protrusions on a side facing the stator, and the armature coil, the field sources, and the soft magnetic members satisfy a relational expression of |M±N|=K. With this configuration, rotors are rotated based on the magnetic modulation principle, so that field poles can have alternating electromagnetic action on the armature coil, and the performance of the electric rotating machine can be improved with a brushless structure.
