Optimal design of a single-phase induction motor considering magnetically balanced operation

In this paper a design condition for magnetically balanced operation in a single phase induction motor is presented in analytic forms. In addition a condition for minimal stator copper is deduced under condition that the balanced operation is satisfied. Using these conditions, an optimal induction m otor is designed by a proper optimization algorithm, and its loss characteristics are investigated. From the results, the va lidity of the proposed method is verified.
