摘要： When an ECU disconnects a second power storage device BAT2 from a drive device 90 while a hybrid vehicle is traveling, ECU disconnects one of a contact point B1 and a contact point G2 of a system main relay SMR2 and causes the vehicle to continue traveling using electric power supplied from a first power storage device BAT1 to drive device. After the vehicle finishes traveling, ECU performs a discharging operation for discharging a charge remaining in a first capacitor C1 and a second capacitor C2 with the one contact point of system main relay SMR2 being disconnected. If the charge is not discharged appropriately, ECU determines that welding occurs in at least one of system main relay SMR1 and system main relay SMR2.

摘要： To provide a disk drive capable of inhibiting the occurrence of acoustic noise caused by a voltage pulse when the head is retracted using a speed control method using voltage obtained by rectifying a back electromotive force after the power source has been cut off from the rotation of a spindle motor. Retraction control circuit is used to control the on and off modes of transistors in accordance with the speed of VCM. The voltage across VCM becomes a voltage that can be regulated with VCM voltage control circuit. At this time, voltage is supplied to the terminals based on the voltage of ISO5V that is the rectified voltage of the back electromotive force of the spindle motor and the pulsating voltage is synchronized and produced at both terminals. As a result, the potential difference across VCM is such that the pulsating voltage is negated and acoustic noise is inhibited.

摘要： A phase voltage setting unit is configured to define an actual current phase region including a current phase error range based on parameters to which is added an individual difference of at least any one of a motor and an inverter. The phase voltage setting unit defines a stable operation current phase region in which a rotor position can be detected through sensorless control, and sets, as a target current, an electric current obtained by adding a phase difference corresponding to the number of revolutions detected by the revolution number detecting unit to an electric current set by current vector control, such that the actual current phase region is within the stable operation current phase region.

摘要： A motor system includes a motor including two Hall sensors configured to output binary values, and a controller configured to control the motor. The two Hall sensors are placed 120 or 60 electrical degrees apart. The controller is operable to monitor output signals of the two Hall sensors and to determine a third Hall sensor output binary value. The controller is operable to fulfill the commanded requirements to operate in a servo system, by controlling commutation of a drive current into the motor, and by keeping track of the motor rotor position based on the third generated signal and the outputs of the two Hall sensors.

摘要： A controller for an AC electric motor, includes a Feed Forward Torque Controller and a load model. The Torque controller directly derives a torque related component of applied motor voltages from a signal representing a torque command input T* and at least one motor parameter. The load model derives a motor speed value including a model of motor speed behavior of the AC electric motor to provide an output signal which represents the motor speed of the AC electric motor. This motor speed output signal is used in determining a frequency of rotation of an applied motor voltage vector. Where an input to the load model is the signal representing the torque command input T*, the load model uses the signal representing the torque command T*, at least over a part of an operating speed range of the AC motor which includes zero speed, to determine the motor speed output signal.
