Abstract:
An electric machine comprising a rotor having a rotor body. The rotor body has multiple poles each carrying at least one rotor winding formed from multiple conductor loops. The poles extend in a radial direction of the rotor and the conductor loops pass through slots each formed between two adjacent poles. A support element extending in the radial direction is arranged in each of the slots between the rotor windings of the adjacent poles. The support element applies pressure to the conductor loops when the rotor rotates and/or heats up. A pressure distribution element extending at least in portions in the radial direction along the support element and the adjacent rotor winding is arranged between the support element and the rotor windings, which pressure distribution element distributes the pressure applied by the support element onto the adjacent rotor winding.
