摘要：The invention relates to an apparatus () for operating a resolver (), which has atleast one receiver winding () or at least one excitation winding (), which are/can beassociated with a rotatably mounted shaft (), in particular a rotor shaft of an electric
motor, said apparatus also having a device () which determines an angular position of theshaft () as a function of an induced voltage detected by the excitation winding () by meansof a desired excitation signal (SES) with a predeterminable frequency and amplitude andby the receiver winding (). According to the invention, means () for limiting an electricalvoltage on the excitation winding () are associated with the excitation winding (), whereinthe means () limit the voltage only above a maximum normal voltage in only one currentdirection.
