Abstract
A magnet configuration for a linear motor includes an array of a plurality of magnets having alternating polarity aligned to define a span. Additional magnets are positioned outside of the span near opposed ends of the span. Each of the additional magnets has a magnetic polarity opposite that of an adjacent one of the plurality of magnets at a corresponding opposed end of the span, such that the array of magnets provides a substantially sinusoidal magnetic field in the span.
