Abstract: A method for identifying a malfunction in an inverter-motor assembly, including a plurality of sequential diagnostic procedures each having the following steps: a step of initially configuring the inverter; a step of initially configuring the phase switches; a step of biasing the phases; a voltage measurement step in which the voltage of each phase is measured; a comparison step in which the voltage measurement of each phase is compared with an expected resultant value; and a step of identifying a malfunction when the voltage measurement of a phase differs from the expected resultant value.

Abstract: A method for determining an estimated current flowing through a winding of a motor that is then controlled on two active phases. A measured voltage is measured for each of the two active phases at the input of the winding, the two measured voltages are corrected to produce a respective corrected voltage, a temperature-compensated resistance of the motor is determined, and at least one estimated current flowing through each of the two active phases, respectively, of the winding is determined on the basis of the temperature-compensated resistance of the motor and the measured voltages of the two active phases.
