distance the first motor component 1 is comprised of an iron core 3 having two legs 4 extending in the direction of the second motor component 2 arranged on each leg 4 is a wire wound coil 5 which may be operated as separate individual coils or as one common coil the second motor component 2 has three permanent magnets 6 that are arranged side by side with antiparallel polarity on a common carrier plate 7 in such manner that one of the magnetic poles points in the direction of the iron core 3 of the first motor component 1 like the iron core 3 the carrier plate 7 is made from an iron material the two motor components 1 and 2 are arranged side by side in such close proximity to each other that only a narrow air gap 8 separates the permanent magnets 6 from the ends of the adjacent legs 4 of the iron core 3 the width of the air gap 8 is dictated by two leaf springs 9 secured to the respective sides of the iron core 3 and the carrier plate 7 one property of the leaf springs 9 is that they act like rigid bodies within the plane spread out by them yielding elastically in a direction perpendicular to this plane for the embodiment illustrated in fig1 this means that in overcoming the restoring force produced by the leaf springs 9 the two motor components 1 and 2 may move relative to each other to the left and right yet they will maintain their relative distance and the width of the air gap 8 remains practically unchanged this results in an oscillatory system in which the first motor component 1 and the second motor component 2.
