Publication number: 20240195274Abstract: A sector roll dipping plant for impregnating rotating components (1) of electric machines in the form of stators and rotors has a roll dipping tank or roller immersion tray (6) that is divided into sectors having impregnating agent inlets (11) which are separated from one another by bulkheads or partition walls (7). At least one sealing element (8) connected to one of the partition walls (7) is in contact with the rotating component (1). A method for impregnating a rotating component (1) (such as a stator or rotor of an electric machine) uses the sector roll dipping plant to cause only the grooves of the rotating component to be soaked with impregnating agent while laminations on the outer jacket surface of the rotating component remain clean.Type: ApplicationFiled: March 8, 2022Publication date: June 13, 2024Inventors: Gerhard Karl MAIS, Karl BAUCH, Christoph MARTIN, Sebastian BAUTZ

Patent number: 7625448Abstract: The invention relates to a device for depositing especially crystalline layers on at least one especially crystalline substrate in a process chamber comprising a top and a vertically opposing heated bottom for receiving the substrates. A gas-admittance body forming vertically superimposed gas-admittance regions is used to separately introduce at least one first and one second gaseous starting material, said starting materials flowing through the process chamber with a carrier gas in the horizontal direction. The gas flow homogenises in an admittance region directly adjacent to the gas-admittance body, and the starting materials are at least partially decomposed, forming decomposition products which are deposited on the substrates in a growth region adjacent to the admittance region, under continuous depletion of the gas flow. An additional gas-admittance region of the gas-admittance body is essential for one of the two starting materials, in order to reduce the horizontal extension of the admittance region.Type: GrantFiled: August 28, 2006Date of Patent: December 1, 2009Assignee: Aixtron AGInventors: Martin Dauelsberg, Martin Conor, Gerhard Karl Strauch, Johannes Kaeppeler
