Abstract
A controller for an axial gap-type motor () comprises a rotor () having a permanent magnet and a first stator () and a second stator () opposed to each other with the rotor () interposed therebetween in the axial direction of revolution of the rotor (). The controller further includes an electrification control portion which supplies a torque current (Iq) for generating a magnetic field to revolve the rotor () to an armature winding () of the first stator () and supplies a field current (+Id) for reinforcing the magnetic flux by the permanent magnet of the rotor () or a field current (−Id) for weakening the magnetic flux to an armature winding () of the second stator (). Consequently, the controllable range of the motor is increased and the axial gap-type motor can be operated at higher velocity and higher torque.
