  • Patent number: 10315690
    Abstract: A method for compensating for a delay in a feedback branch of a servo drive, wherein the servo drive is provided for power-steering a vehicle, includes determining the delay. The method further includes arithmetically compensating for the delay by measuring the spatial expansions of a corresponding metal conductor of the servo drive and the feedback branch. The delay takes place due to formation of eddy currents.
