摘要： A motor includes a rotor including a permanent magnet type rotor unit having a plurality of permanent magnets and a reluctance type rotor unit having a plurality of salient pole portions, the rotor units being coupled to each other in an axial direction. A stator generates a field for driving the rotor. The permanent magnet type rotor unit and the reluctance type rotor unit have an angular deviation therebetween in the direction of rotation to obtain desired torque characteristics. The reluctance type rotor unit has slits for preventing flux leakage from the permanent magnets. The slits are formed with the angular deviation in the direction of rotation from respective positions symmetric about a center of the salient pole portions. Flux leakage is thus prevented to avoid deterioration in characteristics.

摘要： By processing in a control processor 71 signal indicating the amount or degree of pushing-down of the accelerator pedal 2a and signals indicating the non pushing down and full pushing-down of the acceleration pedal 2a, the control unit 7 executes the judgment for determining whether the detected accelerator state is normal or anomalous. In case of judgment of "normal", a usual motor control is executed, whereas in case of judgment to be "anomaly", the system is tentatively designated to be "a state under which the anomaly is being detected". After a specified time lapse, a rejudgement operation is executed, and further when the anomaly is not solved even in this rejudgement operation, the situation is regarded to be a "real anomaly", and an anomaly procedure e.g. to stop current to the motor is executed. When the anomaly state is solved in the rejudgement operation, it is judged to be normal again.

摘要： Provided are semiconductor elements 107A, 107B, and 107C that allow a current to flow that is at most a maximum current determined by the level of control signals VGA, VGB, and VGC and that depends on the difference between the voltage of a DC power supply BA and the charging voltage of a capacitor 102, a controller 105 that outputs a control signal to each semiconductor element, and a temperature detection circuit that detects the temperature of each semiconductor element. Until a predetermined time elapses after the electric circuit is closed, the controller 105 adjusts the level of each control signal based on the temperature detected by the temperature detection circuit so that current through the electric circuit does not exceed a current limit, and after the predetermined time period elapses, the controller 105 adjusts the level of each control signal so that current through the electric circuit is allowed to exceed the current limit.

摘要： A gate voltage detecting circuit 201 detects a gate voltage Vgs of a switching device 11, and when the gate voltage is less than a predetermined voltage that is set to be less than a threshold voltage of the switching device 11, outputs an H-level boost instruction signal. A voltage control circuit 103, when the boost instruction signal is at the L level, outputs a predetermined voltage V1 of a control power supply 102 as it is, and when the boost instruction signal is at the H level, outputs a voltage V2 obtained by boosting the predetermined voltage V1. The drive signal output circuit 104 amplifies a voltage of a PWM pulse output from a PWM pulse output circuit 111 to a voltage output from the voltage control circuit 103. Therefore, a drive signal from the drive signal output circuit 104 to the switching device 11 initially becomes the boosted voltage V2 when the PWM pulse goes to the H level, and then becomes the predetermined voltage V1 when the gate voltage Vgs of the switching device 11 increases to a predetermined voltage. Therefore, a switching loss of the switching device can be suppressed.
