PROBLEM TO BE SOLVED: To constitute a drive system in such a way that the range in which magnetic field is formed for magnetic interactions is limited to the space range in which such actions take places actually or they are required. SOLUTION: This drive system for cars in particular has an electric machine 14 capable of rotating the drive shaft 12 of a drive assembly or (and) obtaining electric energy when the drive shaft 12 is rotating. In this system, the electric machine 14 comprises a stator device 18 and a rotor device 22 coupled or enabled to be coupled to the drive shaft 12 for joint rotation, while the rotor device 22 has a carrier device 98 provided for the coupling to the drive shaft 12 and a rotor mutual action range 92 supported by the carrier device 98. The carrier device 98 has a connected part to the rotor mutual action range 22 or (and) a supporting part 96 having smaller permeability than at least a part 26 of the rotor mutual action range 92 as a part of it.
