Abstract

In order to create a rotating unit for a coating lance device for thermally coating an interior, it is provided that the rotary drive is implemented as a hollow-shaft motor coaxial with the axis of rotation of the tool holder, and wherein the tool holder and the coating material feed, as well as the process media feed, are located centrally relative to the hollow-shaft motor. Furthermore, in order to create a coating lance device for thermally coating an interior, it is proposed to provide such a rotating unit; at least one linear actuator for axial and/or lateral positioning of the rotating unit relative to an interior to be coated; and stationary supply connections for supplying electricity to the coating lance, and for the coating material feed, and for the process media feed.
