Magnet wires wound in slots in a lamination stack of a dynamoelectric machine are encapsulated, in whole or in part, with plastic. The plastic may be thermally conductive and have features molded therein that enhance heat transfer. The plastic may stiffen the armature and increase its critical speed. Characteristics of the plastic, its geometry and its distribution may be varied to adjust spinning inertia and resonant frequency of the armature. The magnet wires may be compressed into the slots, by application of iso-static pressure or by the pressure of the plastic being molded around them. Larger magnet wire can then be used which increases the power of the electric motor using the armature having the larger magnet wire. A two or three plate mold may be used to mold the plastic around the armature. Balancing features can be molded in place.

An armature for an electric motor has a lamination stack on a shaft with a commutator mounted on one end of the shaft. Magnet wires wound in slots in the lamination stack, the commutator and armature shaft are at least partially encapsulated in a first plastic, such as by insert molding. The commutator has a commutator ring divided into a plurality of segments with slots between the segments that are filled with a second plastic when the commutator is made by molding a core of the second plastic, such as phenolic, in the commutator ring before the commutator ring is mounted on the armature shaft. Where the commutator is a tang type commutator, the commutator ring has notches at axial ends of the slots which is filled with the second plastic when the second plastic is molded. The mold used to mold the first plastic includes projections that extend between the tangs of the commutator and against the notches at axial ends of the slots of the commuter. The notches filled with the second plastic and the projections of the mold prevent plastic flash from getting into the slots of the commutator ring. In a stuffer type commutator, the commutator has inserts of insulative material extending part way into the slots of the commutator from an inner end of the commutator. The mold used to mold the first plastic has a portion that seals around the inner end of the commutator ring above the inserts to prevent plastic flash from getting into the slots between the segments of the commutator ring.

A land mine resistant road wheel and track assembly for tracked vehicles which each road wheel includes a center hub surrounded by a plurality of fiberglass support rings whch are, in turn, surrounded by a fiberglass rim member. The entire road wheel is encapsulated in polyurethane which fills the spaces within and between the support rings, but which does not extend into the center hub or into bores aligned with the openings of the support rings, which bores receive mounting bolts for the road wheel. The road wheels are utilized singly and are received in circular grooves formed in the shoes which form the track. The shoes which form the track are made of fiberglass which is molded around a steel yoke. Each steel yoke is provided with a pair of key slots therethrough, each slot of which receives a link that rotates ninety degrees in order to lock in the key slot. Steel pins are utilized to join the links together and, thus, assemble the flexible endless track for use with a plurality of the aforedescribed road wheels.
