The invention discloses a driving winch with a built-in motor, belongs to the technical field of petroleum drilling machine corollary equipment, and solves the problems that a transmission structure of an electric winch is arranged on a winch frame, the overall appearance size is large, the occupied space is large, and the braking torque is large. Mounting holes are formed in the winch frame, two fixing supports are symmetrically arranged on the winch frame, the two fixing supports are connected with roller shafts respectively, bearing mechanisms are mounted on the roller shafts, rollers are connected to the peripheries of the bearing mechanisms, motor mounting seats are connected to the end parts of the roller shafts, and the motor mounting seats are connected with the motor mounting seats. A driving motor is mounted on the motor mounting seat, the motor mounting seat and the driving motor are both mounted in the roller, and a planet wheel transmission mechanism is connected among the roller, the motor mounting seat and the driving motor. The winch is used for lifting and lowering a drilling tool in the drilling process, the motor of the winch is arranged inside, a reduction gearbox is omitted, and a large amount of space is saved.
