Abstract
Method for determining the voltage UL generated by the inductive part of a measuring resistor present in an electronic circuit including a signal generator, at least one stator winding connected to the signal generator and to the measuring resistor and a differential amplifier for the voltage across the terminals of the measuring resistor, the method including: a step of energizing the electronic circuit for a predetermined period of time t; a step of measuring the voltage UT across the terminals of the measuring resistor at the end of the energizing step; a step of determining the voltage UR generated by the resistive part of the measuring resistor at the end of the energizing step; and a step of determining the voltage UL generated by the inductive part of the measuring resistor as a function of the voltage UT and the voltage UR.
