Abstract
An electronic determination device is configured for determining at least one characteristic parameter of an electric machine with P phases, P≥3, connected to an electric starter and including at least P-1 switching arms, each switching arm being connected to a respective phase of the electric machine. The determination device comprises a control module configured to control respective switching arm(s) to close and the other switching arm(s) to open, so as to generate a current injection on two phases of the electric machine; an acquisition module configured to acquire measurements of respective current(s) and voltage(s) for said two phases, further to the generation of the current injection; and a calculation module configured to calculate at least one characteristic parameter of the electric machine according to the respective current(s) and voltage(s) measurements.
