摘要: A motor control apparatus for controlling a motor with reduced noise and vibration includes a detecting means for detecting a rotational speed of the motor, a command signal processing means that generates a command signal for allowing the motor to rotate at a predetermined rotational speed, a drive means that generates a drive signal based on the command signal and supplies the drive signal to the motor, and a control signal generation means that generates a control signal for allowing the motor to produce a control torque having a frequency equal to one of frequencies of noise and vibration due to the motor. The frequency of the control torque corresponds to at least one of orders of the rotational speed detected by the detecting means. The command signal processing means generates the command signal based on the control signal.

摘要: An engine starter includes a starter motor which has an armature, a series-wound field coil and a parallel-wound field coil and a short-circuiting unit for short-circuiting the series-wound field coil under a predetermined engine starting condition. The series-wound field coil has a suitable current limiting resistance. The short-circuiting unit short-circuits the series-wound field coil after a crankshaft of an engine passes a first top dead center of an engine.

摘要: An electric power supply system for a starter comprises a capacitor. This capacitor is charged by a battery through a charging circuit including resistors that charges the capacitor by dividing a voltage of the battery by the resistors. This capacitor is discharged to the starter through a discharge circuit that applies to the starter a charged voltage of the capacitor in addition to the voltage of the battery. When the starter is driven, the connection of the capacitor is switched from the charging circuit to the discharging circuit by an ECU and switching relays.
