Steady state performance evaluation of saturated field oriented induction motors

Steady-state performance characteristics of the stator field oriented control, air-gap field oriented control and rotor field oriented control induction motor drives are compared. Effects of the magnetizing flux saturation on the magnetizing inductance and conductor temperature on the rotor resistance are rigorously included in the performance equations. Key performance indices, such as relative flux level, torque, motor efficiency, and input power factor, are compared when the drive is operating under constant torque and constant speed control.<
