A field replaceable air-gap cartridge armature device for use in rotating electric machines is presented. The cartridge armature includes a plurality of bent-shaped air-gap windings rigidly arranged in a circular fashion to form an inner rim, an outer rim and an active section. The inner and outer rims are formed by end turn sections that are bent toward and away, respectively, from the center of the cartridge device. The windings may be generally arranged into a Z-shaped cross section that is embedded in a fiber reinforced epoxy resin matrix to provide a rigid structure for transferring torque from the air-gap windings to a stator. Countersunk fasteners are used to easily attach and remove the cartridge armature from a rotating electric machine. The cartridge armature can be configured as a three phase, Y-connected armature circuit, and provides electrically insulated, substantially vacuum tight terminal penetration of a rotating electric machine for electrical feed-throughs.
