ABSTRACT:
A power-driven rolling and receiving apparatus includes a housing, a DC brushless motor, a deceleration unit, a motor linker, a control and driving unit, and a first brake unit. The DC brushless motor, the deceleration unit, the motor linker, the control and driving unit and the first brake unit are received in the housing. Two ends of the motor linker are respectively connected with the deceleration unit and the DC brushless motor. The controlling and driving unit is connected with the DC brushless motor. The first brake is located in the controlling and driving unit. Thereby, the dimension of the power-driven rolling and receiving apparatus is smaller, its weight is lighter, its temperature is low and its operation noise is also low.
