The invention discloses a hollow motor and a hollow motor electromobile rear axle, and belongs to the field of transportation vehicles. The hollow motor electromobile rear axle is characterized in that a rotating shaft is in a hollow structure over the entire length, and is directly or indirectly coupled to an input gear of a differential mechanism, and a half shaft penetrates through the hollow structure of the rotating shaft and is connected to an output gear on one side of the differential mechanism. With the adoption of the hollow motor and the hollow motor electromobile rear axle, the possibility of failures such as belt loosening or gap loosing caused by connection between a rear axle differential mechanism and a speed reducer or a motor in the prior art can be reduced, the failures caused by malalignment of the centers of the shafts among the motor, the speed reducer and the differential mechanism can be avoided, , and connection parts are prevented from being influenced by environmental factors.
