A linear drive transport system may include a track that includes first, second, third, and fourth track surfaces that define perimeter boundaries of the track and a magnetic drive system. The first, second, third, and fourth track surfaces include first, second, third, and fourth trajectories about the track, respectively, which are each different from one another. A mover may move along the track and include first and second leading bearings that interact with the first and second track surfaces, respectively, and first and second lagging bearings that interact with the third and fourth track surfaces, respectively, and a reaction element that interacts with the magnetic drive system to generate a propulsive force. The first and second leading bearings may be coupled to the mover at a first fixed distance from one another, and the first and second lagging bearings may be coupled to the mover at a similar distance.

In order to improve the adaptation of a long stator linear motor to requirements or conditions of individual transport units or of the transport track it is foreseen, that a movement profile is preset for the transport unit (Tx), which is followed by the transport unit (Tx), in doing so at least one system parameter of a model of the control system (21) is determined by means of a parameter estimation method, and the value of the system parameter over time is collected and from the variation over time a wear condition of the transport unit (Tx) and/or of the transport track is deduced.

The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereon—regardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.
