In this article, starting from the motor vector control, through expounding the principle of extension control, the extension control is introduced into the motor vector control;then the optimal transformation of coordinates and calculation of the minimum energy consumption in vector control mode are carried out. Based on this, the extension control is optimized, and the classical domain, non-domain and the extension domain are established to form an energy-saving control system of asynchronous motor based on extension-vector coupling, thus three characteristics measurement modes of the control system are obtained. The result shows that the control system can make the motor energy saving get rid of the torque influence, and the effect of motor energy saving is more obvious, which is of great significance in research.
