  • Patent number: 11283310
    Abstract: The invention relates to a stator, an electric machine comprising the stator, a vehicle comprising the electric machine, and a method for producing the stator. The stator comprises a stator laminated core and a housing element. The stator laminated core comprises a plurality of layered stator laminations, wherein each stator lamination has a plurality of tooth portions, each formed radially inwardly at an angular position, and indentations radially outwardly at each of the angular positions, each of which indentations has an at least partially curved edge having two radially outwardly curved edge portions, which meet at a point of intersection and describe an arc of a circle segment. The housing element comprises a cylindrical inner volume, in which the stator laminated core is arranged, the indentations forming cooling channels.

  • Patent number: 11152827
    Abstract: An end plate for a rotor assembly of an electrical machine includes a central through-opening for a shaft, a collar formed on an end face of the end plate on the radial outside in the circumferential direction and a plurality of elevations on the end face. The elevations and collar axially delimit a cooling channel, wherein the cooling channel forms a plurality of cooling channel sections on both sides by a respective elevation. Two elevations delimiting a cooling channel section are spaced apart from one another by a first arc length at a first radial position between the through-opening and the collar and are spaced apart from one another by a second arc length greater than the first arc length at a second radial position delimited by the collar. Each cooling channel section includes at least one fluid guide element between the first radial position and the second radial position.

  • Patent number: 9673672
    Abstract: The aim is to propose an individual-segment rotor that is simple to construct and suitable for series production. Therefore, an individual-segment rotor having a plurality of laminated core segments (2) arranged in a star shape and a permanent magnet (1) between each pair of adjacent laminated core segments (2) is provided, whereby the laminated core segments and the permanent magnets are arranged in a hollow cylindrical assembly. The laminated core segments each have a plurality of individual sheets, which are rigidly connected to one another. The hollow cylindrical assembly has a groove on each of two outer edges, into which groove a ring (11) is inserted in order to fasten the assembly.

  • Patent number: 8917002
    Abstract: An electric machine for installation to a retaining device includes a stator having an axis, and a torque-support device for supporting the stator against the retaining device to prevent a turning movement around the axis. The torque-support device has an intermediate element, at least two holding support elements for providing support against the retaining device, and at least two stator support elements for providing support against the stator. The holding support elements and the stator support elements possess each a greater rigidity in a circumferential direction in relation to the axis than in any other spatial direction.

  • Publication number: 20090285517
    Abstract: A drive facility having an electric motor and a bearing arranged outside the motor for coupling a load shaft to a engine shaft of the electric motor is disclosed. The bearing has an outer ring, an inner ring and several rolling elements which are arranged between the outer ring and inner ring. An axial and a radial force are transmitted by the bearing from the load shaft onto the electric motor. The outer ring of the bearing is connected to a stationary component of the electric motor. The inner ring of the bearing is connected to a rotating component of the motor and is connectable to the load shaft. A torque generated by the motor is transmitted from the engine shaft to the inner ring.
