An electric motor apparatus in a direct drive positioning device for positioning for example a television camera or a robot arm along X-Y-Z axes, which provides a direct drive which permits a free and unobstructed continuous rotation over 300° in horizontal, vertical and any other angular axes with no electrical wires or cables twisting or flexing. The apparatus includes a motor which has a hollow central shaft connected to a rotary member for mounting thereon a robot arm or television camera of the direct drive positioning device. The central shaft encloses a rotating slip ring assembly coupled to respective wires for connecting to the television camera. Electric power is supplied through the wires which are not twisted or flexed while the rotating member is being directly driven by the motor and is rotating.
