The invention is based on a method for controlling a motor, in particular an electrically commutated motor, wherein at least one method step comprises using a control loop () to ascertain a controlled variable () on the basis of which a variation in an operating parameter of the motor is at least partially compensated for. It is proposed that the method comprises at least one adjustment step () that comprises logically combining the ascertained controlled variable () with an adjustment variable () in order to counteract at least one harmonic oscillation of the operating parameter.

The invention relates to a method () for regulating an electric machine (), comprising a harmonic filter (), said harmonic filter () comprising a second filter () and a filter output transformer (). The method has the steps of: ascertaining () a feedback variable (Idq); determining () a filter specification variable (FV); filtering () the filter specification variable (FV); ascertaining () a filtered feedback variable without harmonic components (IdqFunda); and energizing () at least one winding of the electric machine () on the basis of the filtered feedback variable without harmonic components (IdqFunda).

Method and device for regulating an electric machine

In a method for current measurement in a multiphase current network, a conductive connection is produced between a plurality of the phases of the multiphase current network such that the plurality of the phases is short-circuited with one another. At a detection time, a current value flowing between the conductive connection and a first voltage potential is detected.

Method and apparatus of offset error compensation for current measurement in phase lines of a multiphase current network

A supply line structure for supplying energy to electrical components of a motor vehicle, and for the transmission of information between at least a portion of the components (so-called Powerline Communications). To improve the channel characteristics of the information transmission via the supply line structure, it is proposed that the supply lines be arranged in a star configuration having at least one star point, the or each star point an impedance which corresponds to the characteristic impedance of the individual supply line branches running into it. To that end, it is proposed in particular that at the or each star point, an additional series resistor, frequency-dependent for frequencies below 100 MHz, be disposed in the incoming supply line branches. The series resistor is preferably configured as a ferrite sleeve.
