ABSTRACT:
A motor controller (2) for an axial-gap motor (1), which has a rotor (3), two stators (4, 5) disposed on both sides of the rotor (3) in the axial direction, and armature windings (6, 7) wrapped around the stators (4, 5), includes a field current controller (43, 44) which adjusts the field current in the current supplied to the armature windings (6, 7) of at least one of the stators (4, 5) so as to restrain a thrust force acting on the rotor (3) in the axial direction of the rotor (3). This restrains the thrust force acting on the rotor (3) of the axial-gap motor (1).
