    摘要： Motor control device includes a controller controlling a motor (a calculator controller and an electric current controller), and a detector (an electric current loop) detecting an electric current of the motor and returning the detected electric current to the controller. The electric current loop includes a first detection system, a second detection system, and an electric current calculator which sums output signals from each system. Each detection system includes a sensor detecting the electric current of the motor, and a weight adjuster outputting to the electric current calculator, a detection electric current value from each sensor multiplied by a weight coefficient.

    摘要： This method is for controlling an electrical motor, comprising a magnetic rotor comprising at least a couple of magnetic poles, and a stator comprising at least three coils rolled around teeth, said coils being fed in electrical current. The output torque of the motor is controlled by acting on the electrical current provided to the coils. Corrective harmonic currents (M c, i2c, i3c) are provided to the coils to obtain a constant output torque, and are computed on the basis of some characteristics of the electrical motor.

    摘要： A motor control device including a PWM generator generating a PWM generator generating a PWM signal to be outputted to a drive circuit that energizes a winding of a switched reluctance motor; a rectangular wave generator outputting a rectangular wave signal of 1 pulse or more to the drive circuit in 1 drive period of each phase based on a rotational position of the motor; and a drive signal switcher executing switching so that a PWM drive by the PWM signal is performed when a rotational speed of the motor is equal to or less than a threshold value and a rectangular wave drive by the rectangular wave signal is performed when the rotational speed of the motor is greater than the threshold value. The PWM generator synchronizes a timing to start generation of a carrier of the PWM signal with rising of the rectangular wave signal.
