Abstract: An integrated electric drive system and an electric vehicle are provided. The integrated electric drive system includes a motor, a speed reducer, a controller, and a single-piece enclosure. A first enclosure space is formed on the single-piece enclosure, and a second enclosure space and a third enclosure space configured for the speed reducer to be mounted are arranged on the single-piece enclosure. The motor controller is connected with the motor. An output shaft of the motor is connected with the speed reducer. An absolute value of a difference between a preset mounting width value and a width value of the first enclosure space is less than or equal to a first difference threshold. An absolute value of a difference between a length value of the first enclosure space and a length value of the third enclosure space is less than or equal to a second difference threshold.

Abstract: A drive system includes a motor, a speed reducer, a controller, and a housing. The housing includes: a first accommodation space for accommodating the controller; a second accommodation space configured for accommodating the motor; and a third accommodation space configured for accommodating the speed reducer. The controller is connected with the motor, and an output shaft of the motor is connected with the speed reducer. In a length direction of the output shaft, an absolute value of a difference between a mounting width and a width of the first accommodation space is no greater than a first difference threshold. In a direction perpendicular to the length direction of the output shaft and parallel to a horizontal plane, an absolute value of a difference between a length of the first accommodation space and a length of the third accommodation space is no greater than a second difference threshold.
