1. An electric machine, comprising:
a stator having a winding comprising a plurality of conductors assigned to one or more phases, which are interconnected with each other; and
ends of at least two of the conductors associated with one of the phases project axially or radially from the winding at at least one of an inner circumference or an outer circumference of the winding, and are connected to a power connection arranged radially outside the winding by a common connecting conductor;
wherein a plurality of contact elements corresponding to a number of phases are provided on the power connection, said contact elements have a base and at least two fingers protruding therefrom and aligned with the base, the connecting conductor has a contact section with which the connecting conductor contacts on two opposite sides at both of the conductor ends, and the contact section includes two U-shaped receptacles which each encompass one of the conductor ends.
