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.

摘要: A change in torque produced by a motor having two rotors is reduced when the motor operates in a low-velocity and low-torque operational state. The motor has a first rotor and a second rotor, each of which has a permanent magnet, and an output shaft capable of rotating integrally with the first rotor. The second rotor can relatively rotate with respect to the first rotor by a driving force from a phase difference changing driving device, and the phase difference between the rotors (rotor phase difference) can be changed by the relative rotation of the second rotor with respect to the first rotor. When the values of the torque and the rotational velocity of the motor lie within a predetermined region in the proximity of 0, the phase difference changing driving device adjusts the rotor phase difference to a predetermined phase difference for which the strength of a composite field of the permanent magnets is lower than a maximum strength.

The controller includes a first motor operating condition calculator and a second motor operating condition calculator which calculate the estimated values of losses incurred when a first motor and a second motor are driven, and a DC voltage control unit which carries out, on a motor having a largest estimated value of loss, the processing for changing a supply voltage to change the voltage of DC power supplied to inverters by a DC/DC converter, thereby reducing the difference between a phase voltage, which is the resultant vector of the voltages across terminals of the motor, and a target voltage set on the basis of an output voltage of the DC/DC converter.
