Abstract (en)

[origin: DE102006004166A1] The method involves determining two rise times of the phase currents till reaching the predetermined threshold values in an unsaturated condition and by utilizing saturation effects of the rotor (14) and stator irons. The allocation of a magnetic axis to a stator block is determined from a rise time of the currents in the unsaturated condition of the rotor iron and the polarity of the rotor is determined from another rise time of the currents during the current feed with saturation effects. An independent claim is also included for a circuit arrangement for run-up control of an external combustion engine.
