摘要：The electrically excited synchronous generator with YN connection is essential to satisfy the demand of single phase power supply for on-board equipment. But 3 times harmonic of phase electromotive force in YN windings is prominent, aiming to eliminate it, this paper optimizes modulated air-gap in addition to short pitch and distributed windings. To suppress 5 and 7 times harmonics, an analytical model of damping windings is established to optimize the distribution parameters of the damper bars. Finally, the correctness of the analytical model is verified by the finite-element(FE) simulation and the experimental results of the prototype.
