Abstract:
A linear motor is provided including a magnet track including a plurality of permanent magnets, and a coil assembly including a plurality of laminations. The coil assembly defines a plurality of teeth having slots therebetween. The plurality of teeth include (1) two end teeth and (2) at least one non-end tooth arranged between the two end teeth. Each of the two end teeth defines an end profile including a first surface and a second surface. The first surface and the second surface are separated by a step which is substantially perpendicular to a plane defined by the plurality of magnets. The linear motor also includes a plurality of coils at least partially disposed in at least a portion of the slots defined by the plurality of teeth.
