Answer: 1) In the range of ωs≤ωsm, the torque Te is basically proportional to ωs, provided that the air gap flux is constant. 2) Under different stator current values, the air gap flux Ф m can be kept constant by controlling the stator voltage and frequency according to the functional relationship of Us=f(ωs, Is).
