Abstract
The linear synchronous motor consists of a specific primary and secondary part. The secondary portion is a ferromagnetic back plate. An array of permanent magnets are attached to the back plate so that a fixed or variable pole pitch occurs in a precise manner between at least two magnets of alternating polarity which improves existing methods for attaching, guiding, protecting and enhancing the overall flux array produced and emitted by the permanent magnets. A one-piece electrically synchronous linear secondary stator member accompanies a primary member, the synchronous linear permanent magnet motor. The stator electrical frequency is customizeable to allow for a wide variety of braking applications.
