Abstract
An armature for a permanent-magnet linear motor is made up of a set of coils retained in a flat armature plate. The armature plate is of non-magnetic material. In one embodiment, the armature plate is of aluminum having parallel grooves machined in one surface to receive the straight runs of the coils. An aluminum plate covers the grooves to create a reinforcing box-like structure. In a second embodiment, the armature plate is dispensed with and the coils are integrally cast into a resin jacket. A further embodiment employs a serpentine cooling coil for supporting the coils prior to casting the resin and for dissipating coil heat during operation.
