Abstract: A method is described for controlling a multiphase machine which is connected to a battery, the multiphase machine having a DC link which is provided with a DC link capacitor, phase windings, and a high side switch and a low side switch for each phase. The switches associated with the individual phases are controlled by a control unit in such a way that sinusoidal phase currents are predefined, at least one phase current is connected at any point in time in each control cycle, and a fixed, pulsed control pattern is present for each control cycle. The control widths of the actuating signals associated with the phases are constant in the pulsed control pattern. The control pulses associated with the individual phases are predefined in such a way that the DC link current which arises is minimized.

Abstract: An embodiment of a motor controller includes a motor driver and a signal conditioner. The motor driver is operable to generate a motor-coil drive signal having a first component at a first frequency, and the signal conditioner is coupled to the motor driver and is operable to alter the first component. For example, if the first component of the motor-coil drive signal causes the motor to audibly vibrate (e.g., “whine”), then the signal conditioner may alter the amplitude or phase of the first component to reduce the vibration noise to below a threshold level.

Abstract: A method and a control device operate a three-phase brushless direct current motor with phase windings that are fed by an inverter connected to a voltage source having a high potential and a low potential. The semiconductor switches of the inverter are arranged in a bridge circuit and are controlled such that current always flows through two phase windings during motor operation. The motor is operated with normal commutation when the rotational speed is greater than or equal to a minimum rotational speed, wherein the angles are shifted by 60°. During start-up operation, up to the minimum rotational speed, a high-potential-side commutation angle of a phase winding is shifted toward a low-potential-side commutation angle of the phase winding by an angle greater than 0° and less than or equal to 60° with respect to the normal commutation.
