Abstract:
An electric machine comprises a rotor and a stator, wherein the stator comprises a stator body which carries at least one respective winding of at least one phase, wherein the winding of the respective phase or at least one of the windings of the respective phase is conductively connected to a respective contact bridge, which connects the respective winding to an associated power source and/or drain, wherein the respective winding and the contact bridge connected to it each end in a conductor section which extends away from the stator body in the axial direction of the electric machine, these conductor sections being conductively connected to one another, wherein a fixing section of the respective contact bridge is arranged stationary with respect to a housing accommodating the stator by being fixed by an insulation element or directly, on the one hand, to the housing itself and/or, on the other hand, to the power source and/or drain, which, in turn, is fixed to the housing.
