Abstract

A linear motor includes a primary having lamination stacks, which are arranged to realize a polygonal configuration of the primary, and winding coils having windings wrapped about the lamination stacks in parallel relationship to an outer periphery of the primary. Each lamination stack is made of elongate sheets extending in parallel relationship to a center axis of the motor. The lamination stacks are modules that can be combined in any number or arrangement to form a primary best suited for linear motors of desired power output.
