Abstract

Based on the basic principle of the direct torque control of three phase asynchronous motor, this paper analyzes its mathematical model by using the method of space vector, and establishes the basic structure of the direct torque control of asynchronous motor. The direct torque control system is realized by combining the two aspects of hardware and software with the special digital processor (TMS320LF2407) of motor control. When the rated speed of motor is more than 30%, the current waveform of the system is obtained. It can be seen that under steady state, the current waveform of the system is sinusoidal, and the current fluctuates little.
