摘要： A control apparatus for an electric motor provided with a rotator having a permanent magnet and with a stator for generating a rotating magnetic field by an applied voltage and revolving the rotator includes: a rectangular wave inverter that applies a rectangular wave voltage onto the stator of the electric motor to drive the electric motor; a voltage converting section that raises or lowers an output voltage of a direct-current power supply and applies the voltage onto the rectangular wave inverter; an electrical angle acquiring section that acquires an electrical angle of the rotator of the electric motor; and an output voltage command generating section that generates a command for instructing the voltage converting section to output an electrical-angle synchronized voltage whose amplitude ripples in synchronization with a change of the electrical angle of the rotator acquired by the electrical angle acquiring section. In response to the command generated by the output voltage command generating section, the voltage converting section raises or lowers the output voltage of the direct-current power supply to a voltage indicated by the command and applies the voltage onto the rectangular wave inverter. This reduces a loss caused by a response delay of the electric motor.

摘要： A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.

摘要： This electric motor is provided with an inner periphery side rotor, an outer periphery side rotor, and a rotating device that can change a relative phase between these rotors by rotating at least one of them about a rotational axis thereof. The rotating device is provided with a first member integrally and rotatably provided to the outer periphery side rotor, and a second member integrally fixed on an inside of the inner periphery side rotor which together with the first member defines a pressure chamber on the inside of the inner periphery side rotor. The rotating device changes a relative phase between the inner periphery side rotor and the outer periphery side rotor by supplying a hydraulic fluid to the pressure chamber. The rotating device is further provided with a linking passage that leaks the hydraulic fluid supplied to the pressure chamber to an outside of the pressure chamber.

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.

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.
