摘要： A method of controlling an electric motor includes pulsing the electric motor and phase shifting the modulation frequency. Pulsing the electric motor at the modulation frequency propels a vehicle to increase efficiency of the electric motor. Phase shifting the modulation frequency includes phase shifting between 0 degrees and 180 degrees to reduce vibrations induced in the vehicle.

摘要： In a control device controlling a drive circuit that drives an in-vehicle electric motor based on an output voltage of a DC power source, a capacitor for stabilizing the output voltage is disposed between the DC power source and the drive circuit, and a relay switch is disposed between the DC power source and the capacitor. The control device includes: an anomaly determining device that determines whether an anomaly occurs in a vehicle; and a discharge control device that controls the drive circuit to generate a torque at the electric motor based on an output voltage of the capacitor in a state where the relay switch disconnects between the DC power source and the capacitor when the anomaly determining device determines that the anomaly occurs in the vehicle.

摘要： A variable-flux motor drive system including a permanent-magnet motor including a permanent magnet, an inverter to drive the permanent-magnet motor, and a magnetize device to pass a magnetizing current for controlling flux of the permanent magnet. The permanent magnet is a variable magnet whose flux density is variable depending on a magnetizing current from the inverter. The magnetize device passes a magnetizing current that is over a magnetization saturation zone of magnetic material of the variable magnet. This system improves a flux repeatability of the variable magnet and a torque accuracy.

摘要： An ECU sets target value of a system voltage based on an electric power loss of a motor generator and an inverter and controls a voltage boost converter. The ECU calculates the target value of the system voltage using a function expression generated, for each operating point of the motor generator, by approximating a loss characteristic which represents change of the electric power loss with respect to change of the system voltage, by a quadratic expression or a linear expression of the system voltage.

摘要： An object is to provide a driving device capable of detecting a current of a motor without any trouble even in a low rotation speed/low load state to continue a sensor-less vector control, in a case where the motor is driven by the sensor-less vector control, and the driving device comprises: a main inverter circuit for applying a pseudo alternating voltage to a permanent magnet type motor M to drive the motor; a current sensor 6 which detects the current flowing through the motor; and a control circuit which controls the main inverter circuit. Based on an output of the current sensor, the control circuit separates the current flowing through the motor into a torque current component and a field current component to control commutation of the main inverter circuit by the sensor-less vector control. In a case where the motor is operated in a predetermined low rotation speed region and/or the motor is in a predetermined low load state, the field current component is passed in such a direction as to weaken a magnetic flux of a permanent magnet.

摘要： A permanent magnet synchronous machine is controlled according to a d-axis current command Idse* and a q-axis current command Iqse* needed to achieve a desired response of the machine. An actual d-axis current Idse and an actual q-axis current Iqse are sensed and an angular velocity nullr of the machine is sensed. A d-axis voltage command Vdse* is determined using a first proportional-integral regulator responsive to a d-axis current error nullId, a q-axis current error nullIq, and the angular velocity nullr. The first proportional-integral regulator includes a first weighted higher order term comprising a product of a first weighting factor, the angular velocity nullr, and the q-axis current error nullIq. A q-axis voltage command Vqse* is determined using a second proportional-integral regulator responsive to the d-axis current error nullId, the q-axis current error nullIq, and the angular velocity nullr, wherein the second proportional-integral regulator includes a second weighted higher order term comprising a product of a second weighting factor, the angular velocity nullr, and the d-axis current error nullId.
