5. Speed control by frequency variation
5.1 The basics
As the synchronizing speed is proportional to the pulsation ω, it can be varied by varying the pulsation. The question arises as to how the torque-velocity curve will then vary; but this question is meaningless if we don't specify the voltage. Since the equation of a stator phase is :
