Axial gap electric rotary machine

摘要

An axial gap electric rotary machine includes a rotor and a stator that face each other across an axial gap. The rotor is provided with salient poles and permanent magnets that are positioned separately around the circumference of the rotor. Accordingly, north poles and south poles are alternately formed on a surface of the rotor that faces the stator. The magnetic resistance of a magnetic path that passes through the permanent magnets is larger than the magnetic resistance of a magnetic path that does not pass through the permanent magnets. Accordingly, the axial gap electric rotary machine is able to function as a reluctance motor and as a permanent magnet synchronous motor using a single set of facing surfaces of the rotor and the stator, respectively.
