摘要： A method operates a brushed commutator motor of an adjusting drive in a motor vehicle, particularly a window lifter, having a rotor and having a stator. An angular position of the rotor with respect to the stator is determined. The angular position is used to determine a ripple within the torque, which ripple can be expected on the basis of the commutation. The motor current is adapted such that the amplitude of the ripple that can be expected remains below a determined limit value.

摘要： A control device for a rotating electrical machine is provided that is capable of suppressing reduction in controllability of torque attributed to harmonic currents. According to the exemplary embodiment of the present invention, a designated torque value Trq* designated by a hybrid vehicle electronic control unit (HVECU) is corrected by a compensation amount ΔTrq calculated using a harmonic voltage Vh, the designated torque value Trq*, and an electric angular velocity ω as inputs. An operating signal generating section generates an operating signal g¥# using a designated norm value Vn set based on the corrected torque designated value Trq* and a phase δ serving as a manipulated variable for performing feedback control of an estimated torque to the designated torque value Trq*, and outputs the generated operating signal g¥# to a power supply circuit of a motor generator.

摘要： A motor control apparatus has an inverter that applies a voltage to an AC induction motor to be driven, a command value calculator that calculates a command value of an AC voltage outputted from the inverter based on a target motor torque of the AC induction motor, and an inverter controller that controls the inverter based on the command value of the AC voltage. The target motor torque of the AC induction motor includes a first target motor torque and a second target motor torque. A high speed response is required in the first target motor torque in order to at least suppress torsional vibration. The second target motor torque is a lower speed response than the first target motor torque. Delay processing is carried out for the second target motor torque.
