Abstract

A linear motor and side mounted outboard carriage combination comprising an elongate magnetic core (21) having a longitudinal axis, an armature (33), associated with the core and being movable along the axis, plural carriage ways (35, 36) secured on opposite sides of the core, and a carriage assembly (15) mounted on the ways and connected to the armature for movement therewith along the axis, portions of the carriage assembly being mounted on the opposite sides of the core and being so arranged that the center of gravity of the carriage assembly and all elements connected thereto is approximately aligned with the center of force of the core.
