Abstract: In a synchronous linear motor having a traveling field winding which is subdivided into switching sections, each of which is supplied from a converter with current carrying rails of the traveling field winding designed as conductor ribbons with several individual conductors, at a change of switching sections, the individual conductors of the conductor ribbons are interchanged consecutively in such a manner that individual conductors of the one switching section are successively brought out and individual conductors of the next switching section looped in at spacings which are integral multiples of a pole pitch division.

Abstract: The linear motor comprises a stator and an armature mounted for travel along the length of the stator. The stator includes an elongated inner flux-carrying structure extending in the direction of armature travel. A plurality of stationary coils are provided on the inner flux-carrying structure, the stationary coils being spaced in the direction of armature travel. The armature is provided with a plurality of radially magnetized permanent magnet units spaced in the direction of armature travel. The magnetic polarity of successive ones of the permanent magnet units alternates, proceeding in the direction of armature travel from one permanent magnet unit to the next. An outer flux-carrying structure, provided on either the stator or armature, extends in the direction of armature travel and surrounds the armature.

Abstract: A synchronous linear motor having an exciter disposed as a co-moving translator on a track bound vehicle, and having a traveling field winding comprising switching sections which are supplied from a stationary, controlled static frequency changer, wherein the traveling field winding is subdivided into a plurality of individual conductors disposed and connected electrically in parallel so as to reduce the operating reactance. The harmonic content is reduced by an asymmetrical spacing of the individual conductors.

Abstract: A linear induction drive system for an accelerating and decelerating moving walkway comprising a plurality of interconnected platforms that encompass the entire path of travel of the walkway and overlap one another by a small portion of their length in linear constant speed zones and by a substantial portion of their length in acceleration and deceleration zones is disclosed. The linear induction drive system comprises a plurality of stationary linear induction motor stators located in the constant speed zones. Affixed to the platforms are reaction rails formed of a plurality of links rotatably attached to one another such that the links are linearly aligned with one another in the constant speed zones and fold in an accordian manner in the acceleration and deceleration zones. In the constant speed zone the reaction rails are driven by power applied to the linear induction motor stators. Due to the platform interconnection this drive force moves the entire walkway.
