According to one aspect of the utility model, the utility model provides a fan driving assembly which comprises a first impeller, a second impeller and a counter-rotating electric motor. The counter-rotating electric motor includes a drive shaft, an inner rotor and an outer rotor, where the inner rotor is fixedly connected to the drive shaft and the outer rotor is arranged to rotate relative to the drive shaft. A first impeller is fixedly connected to the drive shaft for rotation therewith, and a second impeller is fixedly connected to the outer rotor for rotation therewith. The counter-rotating electric motor comprises a battery fixed relative to a first one of the inner and outer rotors for rotation therewith, the battery being arranged to provide an electrical current to the first one of the inner and outer rotors, thereby rotating the inner and outer rotors in opposite directions. 根据本实用新型的一个方面，提供了一种风扇驱动组件，其包括第一叶轮，第二叶轮和对旋电马达。对旋电马达包括驱动轴，内转子和外转子，其中内转子固定地连接至驱动轴，并且外转子布置成相对于驱动轴旋转。第一叶轮固定地连接到驱动轴以与其一起旋转，而第二叶轮固定地连接
