摘要： A rotating electrical machine control device includes a target current value calculation section, a PWM signal generation section, a voltage application section, and a control section. The target current value calculation section calculates target current values of electric currents supplied to windings of a rotating electrical machine. The PWM signal generation section generates PWM signals for the respective windings based on the target current values. The voltage application section applies voltages to the respective windings based on the PWM signals. When the control section stops driving of the rotating electrical machine, the PWM signal generation section generates the PWM signals in which a timing of a pulse change in the PWM signal of at least one phase is different from timings of pulse changes in the PWM signals of the other phases.

摘要： A motor control device has a three-phase bridge circuit, a driving circuit, and a microcomputer. The three-phase bridge circuit has three pairs of MOSFETs for U, V, and W phases of a three-phase AC motor as a control target. The microcomputer has a dead time set value storage unit and a PWM signal generation unit. The PWM signal generation unit generates a PWM signal with a dead time including a response characteristics of the pair of MOSFETs for each of U, V, and W phases of the AC motor based on a three-phase voltage instruction value supplied from an outside device and the dead time set value stored in the dead time set value storage unit. The PWM signal generation unit outputs the PWM signal for each phase to the driving circuit. This independently adjusts the dead time for the MOSFETs for each phase.

摘要： A control unit for a brushless motor has an upper-arm current detector for detecting an electric current flowing into an upper-arm switching transistor for driving the brushless motor, and a lower-arm current detector for detecting an electric current flowing into a lower-arm switching transistor. The control unit controls the current that flows into the brushless motor based on the upper-arm current value when it is so determined that the lower-arm current value cannot be detected. The control unit detects abnormal condition in the first current detector based on the upper-arm current value.
