Abstract
A contact ring for a stator of an electric motor has three planes, i.e. a first plane with at least one first conductor; a second plane made of an electrically insulating material; and a third plane with at least one second conductor, and at least one first and one second feedthrough passing through the second plane. The first feedthrough is smaller than the second feedthrough, and the first feedthrough guides coil wires of one coil and the second feedthrough guides coil wires of at least two coils.
