When current rises above the second threshold, the voltage is progressively reduced until it reaches some minimum Vmin2 when the current is at some ultimate maximum value I3. When the current is between the first threshold Is and the higher threshold I2, the voltage is set at its maximum value in order to obtain the highest possible output torque. This aspect of the control has the effect of reducing current at light loads, thereby limiting the effects of magnetic saturation which tend to increase current at light loads. The functional relationship may be a straight line function. When the current is below the first threshold Is, the voltage is reduced according to a predefined function so that it is between some minimum voltage Vmin, when current is 0 and some maximum voltage Vmax, when current is at the threshold value Is.
