Abstract: An electric drive unit includes an electric motor, an inverter supplying electricity to the motor, a continuous current stage supplying electricity to the inverter, a controller including a modulator for driving the inverter controlled by a first digital signal representing the amplitude of the phase voltages to be applied to the motor and by a second digital signal representing the electrical frequency of the phase voltages. An analogue/digital stage calculates the optimum value of the advance angle (δopt) of the voltage applied to the motor relative to the counter-electromotive force (“CEMF”) as a linear function of the peak value of the phase current and an analogue/digital stage for measuring the angle (100 act) between the voltage applied to the electric motor and the phase current. The controller is programmed for estimating the angle (γact) between the phase current and the CEMF as the difference between δopt and φact.
