The invention discloses an electric drive propelling system. The system comprises a high-speed heat engine serving as a prime motor, and a high-speed motor, a first electric power converter, a secondelectric power converter and an electro-magnetic gear which are sequentially connected to a rotating shaft of the high-speed heat engine, and the electro-magnetic gear is composed of a high-speed few-pole armature winding connected to the end of the rotating shaft, a magnetism adjusting ring stator and a low-speed multi-pole permanent magnet rotor used for being connected with a low-speed load. The high-speed prime motor and the low-speed load are connected through the electro-magnetic gear, a set of low-power power generation-rectification-inversion electromagnetic adjusting system is arranged on a high-speed shaft system to directly supply power to the high-speed armature winding of the electro-magnetic gear, and the low-speed multi-pole permanent magnet rotor of the electro-magnetic gear adopts a mechanical magnetism adjusting structure, and operates in a weak magnetic mode at a low speed, so that addition of a low-power electromagnetic link enlarges the rotating speed adjusting range of an original system.

    本发明公开了一种电驱推进系统,包括作为原动机的高速热机以及依次连接在高速热机转轴上的高速电机、电力变换器一、电力变换器二和电励磁磁齿轮,所述的电励磁磁齿轮由连接在所述转轴端部的高速少极电枢绕组、调磁环定子以及用于连接低速负载的低速多极永磁转子组成;本发明在高速原动机与低速负载之间采用电励磁磁齿轮连接,又在高速轴系上设置一套低功率的发电—整流—逆变电磁调节系统直接给电励磁磁齿轮的高速电枢绕组供电,电励磁磁齿轮的低速多级永磁转子采用具有机械调磁结构,在低速时弱磁运行,实现了通过增加一个低功率的电磁环节,增加了原系统转速调节范围。
