The invention discloses a motor built-in winch based on a planetary gear train, and belongs to the field of winch braking, the motor built-in winch comprises a base, supporting plates are fixedly installed at the positions, close to the upper end, of the upper surface of the base, a roller is arranged between the two supporting plates in a penetrating mode, and an air cylinder is installed at the position, close to the left end, of the upper surface of the base; the upper end of the air cylinder is fixedly connected with a first arc-shaped fixing plate, and a brake pad is arranged above the first arc-shaped fixing plate. Second teeth are fixedly installed at the position, close to the left end, of the inner wall of the roller, the second teeth are annularly distributed, and the side surfaces of the second teeth are meshed with a plurality of sets of planet wheels. When the winch brakes, the fixing frame is unlocked, the inertia force of the motor rotor is released, meanwhile, the roller cannot be driven to ro
