Abstract: A method for determining the position of a moving rotor in a switched reluctance motor includes the steps of applying a voltage to a phase winding of the reluctance motor, sampling a signal representative of the current magnitude in this phase winding, detecting a feature of the second temporal derivative of the signal, and determining the position of the moving rotor taking into account the occurrence of this feature. Apparatus for carrying out the method is described.
