Abstract
A linear motor primary driven by three phase electrical current is provided comprising a plurality of coils, each having a first and second lead, a plurality of laminations, and a plurality of 'U' shaped conductive connectors, for electrically connecting the leads of the coils. The coils are arranged in poles, each pole having three phases, each phase having a like number of coils. The first and second leads of the coils of a particular phase are aligned in a first and second circumferential positions, thereby forming axial rows along the primary. Coils of a particular phase are connected by connecting leads in the same row with the 'U' shaped conductive connectors.
