The invention relates to a primary-side coil assembly for an inductive energy transfer system for transferring energy between a primary- and a secondary-side coil assembly (A1, A2). The invention is characterised in that the primary-side coil assembly (A1) has four coils (2, SP3, SP4) which form the four adjacent coil regions (BEP1, BEP2, BEP3, BEP4) of the coil assembly (A1), the phase position (&phgr;Ii) of the coil fluxes (SP1, SP2, SP3, SP4) in relation to one another flowing through the coils (I1, I2, I3, I4) determining the phase position (&phgr;&Bgr;i) of the magnetic flux density (Bi) which is established in the regions (BEP1, BEP2, BEP3, BEP4). With the use of a secondary-side coil assembly (A2) comprising four adjacent coil regions (BES1, BES2, BES3, BES4), the phase position (&phgr;Ii) of the coil fluxes (I1, I2, I3, I4) is established such that in the four regions (BEP1, BEP2, BEP3, BEP4) of the primary-side coil assembly (A1), the phase position (&phgr;&Bgr;i) of the respective magnetic flux densities (Bi) which are established is 0°, 90°, 180° and 270° in relation to one another. |
