The invention provides a driving motor comprising a carbon fiber rotor, a power assembly and an electric vehicle. The driving motor comprises a stator and a carbon fiber rotor, the carbon fiber rotor comprises a rotor iron core, a rotor end plate, a fixing piece and a carbon fiber sleeve, and the rotor end plate is arranged between the rotor iron core and the fixing piece in the axial direction of the driving motor. One fixing piece is used for limiting the axial displacement of one rotor end plate relative to the rotor iron core, one side, facing one rotor iron core, of one rotor end plate comprises an annular protrusion, and one annular protrusion is used for abutting against the end face, facing one rotor end plate, of one rotor iron core; a carbon fiber sleeve is used for winding the outer circumferential surface of a rotor core and the outer circumferential surface of an annular protrusion. The carbon fibers of the driving motor cannot be embedded into the rotor to influence the rotor structure, and the performance of the driving motor is improved.
本申请提供了一种包括碳纤维转子的驱动电机、动力总成及电动车辆。该驱动电机包括定子和碳纤维转子,碳纤维转子包括一个转子铁芯、一个转子端板、一个固定件及一个碳纤维套筒,沿驱动电机的轴向一个转子端板排列于一个转子铁芯和一个固定件之间,一个固定件用于限制一个转子端板相对于转子铁芯的轴向位移,其中:一个转子端板朝向一个转子铁芯的一侧包括一个环形凸起,一个环形凸起用于抵接一个转子铁芯朝向一个转子端板的端面,一个碳纤维套筒用于缠绕一个转子铁芯的外周面以及一个环形凸起的外周面。该驱动电机的碳纤维不会嵌入转子内对转子结构产生影响,有利于提升驱动电机的性能。
