Abstract
An arrangement and methods for operating and for determining the speed of an electrical machine connected to a power electronic switching device and for supplying energy to a control device of the power electronic switching device. The arrangement and methods have an inductive decoupling device arranged on an electrical conductor leading from the switching device to the electrical machine, wherein a frequency determination device is used to determine the frequency of a voltage associated with a current in the electrical conductor and thus indirectly the speed of the electrical machine, and wherein a rectified output voltage of the decoupling device forms a voltage source for the control device.
