摘要
本文用有限元法对大型凸极同步电机的空载主极磁场进行了仔细的计算,得出了??这一范围内主极磁场的波形系数k_φ,极弧磁通系数k_λ,基波和谐波(到19次谐波)幅值系数的具有较高精度、较广范围的新曲线,供设计和研究工作者使用.
In this paper, the non-load magnetic field around the pole in large salient-pole synchronous is calculated carefully by the finite element mechod. The new curves of the flux distribution coefficient K_ф, pole face flux coefficient K_λ, fundamemtal and harmonics (until nineteenth) of the non load flux wave in the air-gap are got. These curves with higher precision and widcr range can be used by designers and reseachers, which range over b_p/τ=0.4～0.8,δmax/δ=1～3, δ/τ=0.005～0.055.
