Abstract (en)
[origin: DE102006046637A1] The device has a voltage measuring device (6) and a difference providing device (8) for evaluating a measuring signal that is controlled by changing inductance of a pole coil of phase cables (1-3) of an electrical machine due to current flow by the phase traces for production of status information. The device (8) determines voltage difference values, where a comparison and classification device (9) determines rotation angle interval that is defined for a rotation condition of a rotor of the machine.
