Sector Roll Dipping Plant

A sector roll dipping plant apparatus for impregnating a rotating component (1) such as a stator comprising a laminated core (4) and a current-carrying winding (2), a winding head (3), or a rotor comprising a laminated core (4) and a winding (2) of an electrical machine, comprising:

• a roller immersion tray (6) that is divided into two or more sectors with impregnating agent openings (11), which are separated from one another by one or more partition walls (7), wherein at least one sector is filled with impregnating agent (12) to a desired filling level and at least one adjacent sector is unfilled with impregnating agent, and wherein the roller immersion tray (6) in at least one sector defines impregnating agent openings (11) configured to pass impregnating agent (12) into and out of the at least one of the sectors of the roller immersion tray (6) that is filled with impregnating agent (12), and at least one sealing element (8) that is connected to or formed on at least a respective one partition wall (7) and that is in contact with the outside of the laminated core (4) of the rotating component (1), so that with at least a Portion of the outside diameter of the laminated core (4) of the rotating component (1) is positioned in the unfilled sector of the roller immersion tray (6), impregnating agent (12) in the filled sector of the roller immersion tray (6) flows into the winding (2), winding head (3) and existing grooves of the laminated core (4) of the rotating component (1) without contacting lateral surfaces of the rotating component (1) designated to remain free of impregnating agent (12).
