Abstract
An axial motor includes an armature side stator (), a pair of rotors, and a pair of stators, which are arranged with gaps left therebetween in the axial direction of a drive shaft (). The armature side stator () includes armature coils (). The pair of rotors are a first rotor () and a second rotor () that are arranged on both sides of the stator () and include inducers (). The pair of stators are a first field side stator () and a second field side stator () that are arranged respectively on oppositely spacing sides of the first rotor and the second rotor. The first and second rotors () are mounted to the drive shaft (). The first and second field side stators () include respectively first and second field coils () arranged in a toric form about the axis of the drive shaft (). The first and second field coils () are supplied with currents in opposed directions such that magnetic fluxes are generated in the first and second field coils () in opposed directions.
