First Claim
1. A synchronous linear electrical machine operating as a motor or an electrodynamic brake consisting of an array of at least two permanent magnets 1 of alternating polarity;
- the magnets 1, being attached to a ferromagnetic back plate 2, that has precision machined countersunk slots 3, to accept the permanent magnets 1, in such a manner that will allow for highly accurate pole pitch, spacing along the magnetic array 1. The countersunk slots 3, surround and keep the highly attractive magnets 1 in place;
a one-piece non-ferromagnetic conductive material, ladder type, frame 4 laminated to an identical one-piece conductive type frame 5 and then welded into a non-magnetic, case 6. The frames 4,5 being blind drilled and tapped to match the bolt pattern 10 of the ferromagnetic back plate 2. Secondary synchronous stator member.

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.
