A coaxial propulsion system is provided, which comprises a housing, and two or more electric motors provided in the housing, wherein the electric motors share one common shaft. At least one of the two or more electric motors is a permanent-magnet synchronous motor, an asynchronous motor or a switched reluctance motor, and of different efficiency maps. The system can improve the power density and system efficiency of propulsion system while maintaining high performance output, to enhance the integration level, and reduce size, weight and cost.
