Abstract: The invention relates to an inductive energy transmission system for the transfer of electrical energy between a base station and a movable consumer, in particular a vehicle, the energy transmission system being able to transfer electrical energy from a base station to the consumer and/or from the consumer to the base station, said energy transmission system comprising at least one primary-side flat coil (Sp), arranged in the base station, and a flat coil (Ss) arranged on the secondary side in the consumer, having a plurality of turns (3, 4) in each case, the turns (3, 4) being arranged concentrically or spirally around a centre (M), characterised in that there is a relative spacing (d1) at least between some adjacent turns (13) of a primary-side flat coil (Sp), and the distance (9, 10) between the turn arranged closest to the centre (M) and the turn arranged furthest from the centre (M) in the primary-side coil (Sp) is greater than in a secondary-side coil (Ss).

Abstract: An electrically commutated motor comprises a plurality of stator phases and a rotor. Further, sensors for detecting the control deviation of the rotor in relation to the stator phases are provided. A phase control unit controls the stator phase rotary field depending on the detected control deviation. The phase control unit comprises a single-phase controller for a single-phase mode of operation, and a multiple-phase controller for a multiple-phase mode of operation. Further, a control deviation evaluation element is provided which evaluates the magnitude of the control deviation, and selects, depending on the evaluation result, the single-phase mode of operation or the multiple-phase mode of operation.
