Abstract: An axial gap rotating electrical machine is provided with permanent magnets and cores in a rotor. The permanent magnets are oriented such that magnetization surfaces face in the circumferential direction of the rotor. The cores are arranged alternately with the permanent magnets in the circumferential direction of the rotor.

As a result, the magnetic flux density at the rotor cores can be made substantially constant in the radial direction of the rotor and torque output with respect to the size of the permanent magnets is improved by preventing magnetic saturation of the cores.

Abstract: 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.
