Abstract: A winch includes a rotatable drum. A cable is wound onto the drum in one rotative direction and off the drum in a second rotative direction. A sealed axial flux permanent magnet drive motor includes a drive shaft selectively rotated by the motor in either direction of rotation. A gear train interconnects the drive shaft and the drum for rotatably driving the drum at a reduced rotative speed relative to the motor shaft. The motor can apply regenerative braking. A spring- applied electric release brake is connected to the drive shaft to apply a braking force to prevent rotation of the drum. A connecting shaft connects the gear train to the rotatable drum. The connecting shaft includes axially spaced splines that reduce the disparity in the gear train and drum centerlines to thereby reduce gyration therebetween. The drum can be made partially from carbon fiber to reduce the weight thereof.
