The invention discloses a motor driving structure and an electric vehicle with the motor driving structure, and relates to the technical field of motor drive.The motor driving structure comprises a machine shell, a rotating shaft is rotatably inserted into the machine shell, a stator is arranged in the machine shell, and the rotating shaft is sleeved with a rotor corresponding to the stator; one end of the rotating shaft extends out of the machine shell and is connected with a speed reducer, a hollow hub ring is arranged at one end of the machine shell, and the speed reducer is located in the hub ring. A brake assembly and an encoder assembly are arranged at the other end of the rotating shaft; one end of the hub ring is rotationally connected with the end of the machine shell, and the other end of the hub ring is provided with a first end cover. The speed reducer comprises a first-stage planetary reduction gear assembly and a second-stage planetary reduction gear assembly. According to the technical scheme, size miniaturization and light weight of a motor driving structure in equipment such as a high-power heavy-load electric vehicle are achieved; the rigidity and the supporting strength of the motor driving structure are improved, and stability and reliability are achieved.
