Abstract
A multiple linear motor arrangement is provided having a secondary, a first primary, a plurality of second primaries, and a frame, in which the body of the first primary of the motor arrangement on one side of the secondary is offset from the bodies of the second primaries on the other side of the secondary. Magnetic flux emanating from the first and second primaries, therefore, does not appreciably overlap.
