  • Patent number: 10622857
    Abstract: An electrical machine includes a first active part and a second active part. Both the first active part and the second active part have a plurality of laminated sub-cores, with each laminated sub-core having a plurality of individual laminations. Each lamination is defined by an axial width. The laminated sub-cores are mutually spaced in an axial direction such that a respective radial cooling slot is formed between two adjacent laminated sub-cores. The radial cooling slots in the first active part are offset in the axial direction in relation to one another in comparison to the radial cooling slots in the second active part, and the sum of the axial widths of all individual laminations in the first active part corresponds to the sum of the axial widths of all individual laminations in the second active part.

  • Patent number: 9222590
    Abstract: The present invention relates to a ventilating and evacuating valve for fluid-guiding conduit pipes or braces. The valve includes a valve mechanism and a floating body which acts on the valve mechanism. The valve mechanism includes a valve body which can be moved into different opening or closing positions in order to open and close a valve outlet; a diaphragm cup; and a roll diaphragm which is arranged between the valve body and the diaphragm cup and can come to rest in different opening or closing positions over aperture openings of the valve body. The valve also includes a channelling mechanism which is configured to guide an evacuating flow past the valve mechanism.
