我们曾经发布的一条内容中,有用户咨询如下问题,请帮忙解答:

双馈异步风电机组为什么采用三分之一变流器?永磁直驱风电机组为什么采用全功率变流器?

https://www.zhihu.com/question/464757300/answer/2318966162

请问为什么双馈电机不能通过增加极对数来降低额定转速,从而降低变速箱的压力呢?

Hi Bellawu,

理论上来说可以,但极对数增加电机尺寸变大,这会增加电机本体制造成本,一定功率下,电机和变速箱需要配合折中,保证成本和尺寸满足应用要求。而且电机和变速箱的选择需要综合考虑两个部件的成本、制造工艺、机械安装和机舱振动等多方面因素。

Best regards,

Rachel
