Electric drives for automobiles require at low speed for starting a torque which is a multiple of the rated torque, and for above rated speed a torque which is about the rated torque. Known (V/f) control results in a decreasing torque above rated operation while the (V · p)/(f · N) control -where the terminal voltage V = Vt is less or equal to Vrated, the number of series turns of the stator winding N is less or equal to Nrated - increases torque, speed operation, and power rating.
