Induction motor efficiency maximizing based on torque per power index

<span>In this paper, efficiency maximization of induction motor variable frequency speed regulation system based on torque per power (TPP) index is proposed. The detail the mathematical model considering iron loss and rotor field orientation, relationship between ratio slip presented. functional derived, derivative obtained to find optimal corresponding maximum value. simulation experimental platform control were built in Matlab/Simulink verify effectiveness method. result approved takes value, high energy operation with minimum realized.</span>
