Abstract
An electrical machine includes an angular position transducer for identifying a first rotation angle of a rotor; a stator winding for generating a magnetic field; a voltage measuring instrument for sensing a pole wheel voltage at the ends of the stator winding upon a rotation of the rotor; and an identification circuit for identifying a second rotation angle from the pole wheel voltage and for identifying an angle difference between the first and the second rotation angle.
