Controlling the Number of Revolutions of the Asynchronous Machine at Maximum Torque

In this paper, it is shown the possibility of maximizing the torque independent of the asynchronous machines number of revolutions inconditions where the limit value is not exceeded for flux and the current from the stator puddening. The method is based on the orthogonal model of the asynchronous machine together with the algebric system generated by the Lagrange function.
