  • Patent number: 6365999
    Abstract: The invention relates to a stator module for an electric motor, especially an electric motor with transverse flux, comprising at least one stator unit that consists of at least one armature winding and which, when mounted, is associated with a rotor, whereby an interferric space is created in a radial direction in relation to the axis of symmetry of the electric motor.

  • Patent number: 5777418
    Abstract: A transverse flux motor includes an outer stator having a plurality of outer stator soft iron elements which are substantially disposed with uniform separation from one another. The flux motor further includes an inner stator having a plurality of inner stator soft iron elements. The inner stator further includes at least one anchor winding. The motor has a rotor which, looking at it in a section perpendicular to the axis, is built of alternating magnets and soft iron elements. The outer stator is free from anchor windings. Also, the outer stator soft iron elements are disposed in such a way that at least one gap region is provided which is larger than the space provided between the remaining neighboring stator soft iron elements. At least indirect means are provided in this region to compensate magnetic end effects.
