Three-level direct torque control of salient pole synchronous motor

The mathematical model of salient pole synchronous motor has been given. The principle of three-level direct torque control of salient pole synchronous motor is analysed. The synthesis method principle of virtual synthesis phase has been given in detail. Some simulation waveforms which based on the virtual synthesis method of three-level direct torque control of salient pole synchronous motor have been given. The simulation results show that the program has some advantages, such as low torque ripple and fast response. So it has some actual value.
