This paper analyzes the vector control theory of asynchronous motors based on the magnetic orientati

This paper analyzes the vector control theory of asynchronous motors based on the magnetic orientation of motor rotors, and its mathematical model is made. Then the variable frequency vector speed-adjusting experimental system is built with the DSP TMS320F2812 which works as the core control chip an ...
