  • Patent number: 10680497
    Abstract: The invention relates to a housing (10) for an electrical machine (50) and to an electrical machine (50) having such a housing (10). The housing (10) comprises an inner wall (12) and an outer wall (14), with a hollow space (16) therebetween for cooling the electrical machine (50) with a fluid. The housing (10) further has a sealing device (24, 26) on a front face (22, 23) of the housing (10). The housing is particularly characterised in that the sealing device (24, 26) comprises an annular sealing element (28) mounted between the inner wall (12) and the outer wall (14) so as to seal the front face, and in that the sealing device (24, 26) comprises a deflection ridge (30) which projects from the sealing element (28) in the axial direction of the housing (10) and is at least partially arranged between the walls (12, 14), the deflection ridge (30) being designed to lead a cooling fluid in the hollow space (16). A compact, economical and fluid-tight housing (10) can thus be advantageously provided.

  • Patent number: 10476343
    Abstract: The invention relates to a heat sink (1) for an electric machine, which heat sink has at least one cooling channel (7), which adjoins an interior (3) surrounded by the heat sink (1). The heat sink (1) is characterized in that the heat sink (1) is designed as a single-piece plate (5) bent into a closed ring, in the case of which plate two opposite abutting surfaces (19, 21) are connected to each other in a fluid-tight manner in the region of a joint (17), wherein a plurality of closed channels (7) extend in the plate (5), which channels extend at an angle to the circumferential direction of the ring in such a way that adjacent channels (7) lead into each other in the region of the joint (17) and thus form a continuous, spiral channel, which extends in a plurality of spiral turns from an axially front end (22) to an axially rear end (24) of the annular heat sink (1).

  • Publication number: 20130270949
    Abstract: A permanent magnet electric machine (2), in which permanent magnets (7) are arranged on a stator (13) and/or a rotor (15). In this case, a permanent magnet (7) has at least one first macroscopic permanent magnet element and one second macroscopic permanent magnet element (21, 23), wherein the permanent magnet elements (21, 23) are formed from different materials, which have different magnetic coercitivities.
