Abstract The traditional direct torque control, under the premise of keeping the stator flux amplitude constant, changes the stator flux phase to adjust the torque. For the synchronous reluctance motor direct torque control scheme and the low power factor, this paper proposes a synchronous magnetic reluctance motor space space vector direct torque control (SVM-DTC) scheme with variable flux linkage amplitude, by changing the flux linkage amplitude. The power angle is adjusted to improve the power factor, and the shortcoming of the direct torque control power factor is overcome. The SVM-DTC model of synchronous reluctance motor was built by Matlab/Simulink, and two direct torque control schemes of constant flux amplitude and variable flux amplitude were verified. The results show that this scheme can significantly improve the power factor compared to the traditional SVM-DTC.
