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.
