Abstract: Accurate calculation of leakage reactance is key to design of electric machine. The calculation of leakage reactance of dual stator-winding induction generator with excitation regulator is more complex than ordinary 3-phase machine. In this paper, the general mathematic model and equivalent circuit of dual stator-winding induction machine are proposed. The analytical calculations of leakage reactance of dual stator-winding induction machine with different winding structure are presented systematically, the relevant formulas are derived. Finally, a dual stator-winding induction generator with excitation regulator is designed, and its leakage reactance, characteristics and performance are calculated.

Key words: dual stator-winding induction machine, leakage reactance, parameter’s calculation, electric machine design
