Maximization of Electromechanical Performance of a Squirrel-Cage Induction Machine in a Fixed Active Part Volume

The existing approaches to constructing the dependences of key technical and economic indicators of induction machines on their main dimensions are listed. An approach based on a series of optimization calculations of energy-efficient induction machines within rational ranges of the main dimensions is proposed. The obtained data are compared with the corresponding indicators from classical design guidelines. Recommendations are given for the practical use of the results in the design of series of energy-efficient induction motors.
