Abstract:
The amplitude of stator flux linkage and torque angle are controllable variables in non-salient pole permanent magnet synchronous motor,and the interaction effect of stator flux linkage amplitude and torque angle is Q-axis flux linkage.Taking the permanent magnet synchronous motor with Y connected stator winding for example,a novel direct torque control method through the control of Q-axis flux linkage is presented.This method selects the required voltage vector according to the torque control requirement directly without constant stator flux linkage amplitude control and complex coordinate transformation.The correction and feasibility of the proposed method are verified by the simulation results.
