摘要
针对航空多相永磁同步发电机需要通过弱磁控制来满足宽转速范围下的恒压供电问题,经过对多项参数的分析,得到了参数与双Y移30°内置式永磁同步发电机弱磁运行时转速的关系,并通过对恒定功率供电状态进行详细分析,说明了减小永磁体磁链和改变凸极率对于拓宽发电机允许运行转速具有显著作用,为电机的选型与设计提供了参考。
Aiming at the problem of constant voltage power supply in the wide range of rotating speed,the aircraft multi-phase permanent magnet synchronous generator needs to be controlled by flux weakening method to meet the requirement of constant voltage power supply.Through the analysis of several parameters,the relationship between parameters and rotating speed of the dual Y shift 30 degree internal permanent magnet synchronous generator under flux weakening control was obtained.With the detailed analysis of the constant power supply state,it is shown that reducing the permanent magnet flux and changing the salient pole rate play a significant role in widening the allowable running speed of the generator,which provides a reference for the selection and design of the motor.
