Patent ID: 11502591

Abstract:
The invention relates to an electric motor having at least one magnetic track, which has a plurality of magnet elements connected in a line in a longitudinal direction or in the shape of a ring, in particular in a Halbach array configuration, and having at least one coil assembly, which includes a support that is substantially electrically and magnetically non-conductive with respect to the magnetic track, which is configured such that the coil assembly and the magnetic track are capable of carrying out a guided movement relative to each other, and which includes at least one group of three conductive flat coils. Each of the three flat coils is connected to one phase of a three-phase power supply, and the conductor tracks of the three flat coils of the group or of each group are arranged so as to be nested in each other or overlap with each other on a first and second support conductor plane, which are electrically insulated from each other by an insulating intermediate layer, such that parts of the conductor pattern of each of the three flat coils are designed to be connected one over the other and together in parallel on the first and second conductor plane and two of the three overlapping flat coils in each case have crossover regions in which the conductor tracks of the first flat coil only run on the first support conductor plane and the conductor tracks of the second flat coil only run on the second support conductor plane.
