A track bound electric vehicle, particularly a train or tram, comprises a device adapted to receive an alternating electromagnetic field and produce an alternating current by magnetic induction. The receiving device comprises a plurality of phase lines, each forming at least three coils and each coil consists of at least one turn of the phase line. The at least three coils of each phase line are located next to each other so as to form a sequence (G, R, B) of coils (GCL, GCM1, GCM2, GCR; RCL, RCM1, RCM2, RCR; BCL, BCM1, BCM2, BCR) which covers an effective area in a plane that extends perpendicularly to the central axes of the coils, so that there are a first (GCL; RCL; BCL) and a second (GCR; RCR: BCR) end coil at the opposite ends of the sequence and at least one middle coil in between the end coils of the sequence. For at least one of the phase lines, each of the end coils consists of a smaller number of turns than the middle coil or middle coils. |
