1. A linear motor comprising:
- a magnet track;
a magnet assembly coupled to the magnet track, the magnet assembly having a plurality of side-by-side alternating magnetic north poles and magnetic south poles; and
an armature having a plurality of side-by-side electrically conductive coils formed on an electrically and magnetically nonconductive substrate which is movably coupled to the magnet track such that the side-by-side electrically conductive coils are positioned and movable in spaced parallel relation to the side-by-side alternating magnetic poles, the substrate including a plurality of electrically nonconductive layers laminated together, each layer having a plurality of electrically conductive windings formed thereon in side-by-side relation on at least one surface thereof with adjacent conductive windings of each layer electrically isolated from each other on the layer, each electrically conductive winding of each layer positioned in registration and electrically connected with a corresponding electrically conductive winding on each other layer to form one of the electrically conductive coils.

Abstract
A linear motor includes an armature having a plurality of side-by-side electrically conductive coils formed on an electrically and magnetically nonconductive substrate with adjacent coils electrically isolated from each other. Each coil includes a plurality of electrically conductive windings positioned coaxially and electrically connected so that in response to an electrical current flowing therethrough each winding produces a magnetic field having the same polarity. Each electrically conductive winding of each coil is preferably formed on a layer and a plurality of layers is laminated together to form the substrate.
