This paper proposes an algebraic and a graphical method for finding all the performance extreme values of a three-phase induction machine when it operates as a motor or a generator. The performance extreme include maximum efficiency‚ maximum power factor‚ maximum electric power‚ maximum torque and maximum mechanical power in both motoring and generating modes. In addition to the algebraic method‚ this paper shows how an old graphical method can be used to accurately find the performance extreme values
