  • Patent number: 11735981
    Abstract: An electrical machine includes an interconnection assembly that creates contact for a stator of the electrical machine, a busbar that creates contact for the interconnection assembly, a measurement printed circuit board that is arranged perpendicularly to an axis of rotation of the electrical machine, on a side of the interconnection assembly that is averted from the stator, wherein a field sensor is arranged on the measurement printed circuit board, and a flux concentrator that engages around the busbar and the field sensor.
    Type: Grant
    Filed: October 28, 2021
    Date of Patent: August 22, 2023
    Assignee: Robert Bosch GmbH
    Inventors: Marie-Luies Schoeneck, Michael Mayer, Patrick Fruehauf, Wolfram Kienle

  • Patent number: 10749399
    Abstract: Stators for an electrical machine which are fitted with a polyphase winding which is in the form of a plug-type winding and the winding sections of which run through slots of the stator and comprise a plurality of different conductor elements are already known. At least some of the said conductor elements have in each case two conductor limbs and in each case one connecting conductor which connects the two conductor limbs, wherein an even number of n conductor limbs is arranged one above the other in the radial direction with respect to a stator axis in each slot. Each conductor limb of one of the conductor elements is provided in its slot in a specific position with respect to a slot base of the slot. These polyphase windings comprise a comparatively large number of different conductor elements, in particular so-called special conductors which differ from the standard conductor elements. These special conductors increase the manufacturing costs.
