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. The amount of magnetic flux on the outside in the radial direction of the rotor is made greater than the amount of magnetic flux on the inside in the radial 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.
