摘要： A controller for an axial gap-type motor (3) comprises a rotor (11) having a permanent magnet and a first stator (12a) and a second stator (12b) opposed to each other with the rotor (11) interposed therebetween in the axial direction of revolution of the rotor (11). The controller further includes an electrification control portion which supplies a torque current (Iq) for generating a magnetic field to revolve the rotor (11) to an armature winding (13a) of the first stator (12a) and supplies a field current (+Id) for reinforcing the magnetic flux by the permanent magnet of the rotor (11) or a field current (−Id) for weakening the magnetic flux to an armature winding (13b) of the second stator (12b). Consequently, the controllable range of the motor is increased and the axial gap-type motor can be operated at higher velocity and higher torque.

The controller has a demagnetization determining means for determining whether or not demagnetization of the permanent magnets of the rotors occurs during operation of the motor, and rotor phase difference controlling means for controlling the phase difference changing driving means to change the phase difference between the rotors from a current phase difference to a phase difference that results in a higher strength of a composite field of the permanent magnets if the result of determination by the demagnetization determining means is positive.

摘要： A controller for a motor cleans, as necessary, a hydraulic chamber that generates hydraulic oil for changing a phase difference between two rotors so as to restrain sludge from building up in the hydraulic chamber. A motor has a first rotor and a second rotor that can be relatively rotated with respect to the first rotor. The controller includes a phase difference changing driver that changes the phase difference between the two rotors by controlling the pressure in the hydraulic chamber filled with hydraulic oil. The controller further includes a cleaning need determiner that determines the need for cleaning the hydraulic chamber, and a cleaning phase difference controller that controls the phase difference changing driver such that the second rotor is relatively rotated in the forward direction and the reverse direction alternately with respect to the first rotor if a determination result of the cleaning need determiner is affirmative.
