    The potential for high force and low inertia makes the long stator linear induction motor a good candidate for use in aircraft launch. These motors typically have a segmented stator that runs the entire length of travel. A conductive plate is used as the moving shuttle. If high reliability is desired, one approach is to drive shuttle plate using multiple, separately excited stators. Although the s... View full abstract»

    Linear synchronous motors present both advantages and challenges when used to control vehicles on a guideway. It is often advantageous to split a stator into small segments and drive each segment independently, but this strategy introduces complications not found in single stator systems. Distinctions include stator back-electromotive force variation with vehicle position, vehicle thrust constant ... View full abstract»
