Title:
AXIAL-GAP MOTOR
Document Type and Number:
WIPO Patent Application WO/2016/075728
Kind Code:
A1
Abstract:
The purpose of the present invention is to increase the output torque while suppressing the electric current fed to a stator in an axial-gap motor with one stator and two rotors. The axial-gap motor is configured from: a stator that has a plurality of stator core members, each member comprising a core for carrying a magnetic flux and a winding wire wound around the outer periphery of the core, arranged in a ring shape around the rotation axis; a first rotor that has magnets having different polarities alternatingly arranged on the surface facing, with a gap therebetween, one axial end face of the stator; and a second rotor that has a surface facing, with a gap therebetween, another end face different from said end face and that has reluctance that varies according to the rotation angle.
