摘要： A method of fabricating a commutator for a motor comprises the steps of: drawing a bar into the shape of a plate; forming plural commutator segments having a predetermined size by cutting the plate at appropriate intervals; heat-processing the commutator segments with liquefied nitrogen; inserting the heat-processed commutator segments, and setting the commutator segments in a mold in a circular pattern having a predetermined gap from one another for receiving insulating resin, and inserting a bushing in a central position of the circular pattern of commutator segments; forming an insulating resin layer in the gaps between the commutator segments by extruding or injecting an insulating resin into the mold; and finishing an inner diameter and an outer diameter of the fabricated commutator.

摘要： A rotor for a small-sized motor has a plurality of rotor magnetic poles and a commutator on a rotor shaft, and both ends of a wire of each winding of the rotor magnetic poles are tied up with and connected by spot welding to a U-shaped hook-type commutator leg connected to the corresponding commutator piece end of the commutator, respectively. The commutator leg has a copper-based base material, and is composed by attaching a thin layer of a clad material with a melting point lower than that of the above described base material and a high electric resistance thereon at the surface part to be inside when bent to the U-shaped hook type. Thus, in the connection between the commutator leg and the copper wire material of the small-sized motor, the reduction of defectives of breaking of the wire because of heat shock at the time of welding is achieved, and in the meantime, the stabilization of welding is achieved, so that the reliability of the connection can be increased.

摘要： Each of the rotor magnetic poles is composed of a winding around a laminated core and each of both ends of each wound wire is connected to a commutator leg part coupled with a tip of a corresponding commutator segment of the commutator unit. Each of the commutator leg parts includes a base portion extending outward in a direction substantially normal to the radial direction from the tip of the corresponding commutator segment tip and coupled to the commutator segment top and a tip portion narrowed stepwise to let the ends of a wound wire be connected. A disk-shaped varistor having a hole at the center is mounted over the base portion of the commutator leg part, and each electrode of the varistor is soldered onto the corresponding base portion. Further, the commutator leg parts are punched and cut out of a reel-wound flat parent metal sheet and fixed to the commutator segment tips.

摘要： 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. The plastic can have a base polymer that is a blend of two or more polymers and various thermally conductive fillings.

摘要： Magnet wires wound in slots in a lamination stack of a dynamoelectric machine are encapsulated, in whole or in part, with thermally conductive plastic. Pre-formed features having a thermal conductivity higher than the thermally conductive plastic are insert molded when the plastic is molded. The pre-formed features may include a finned end cap and a fan. Alternatively, end domes of the plastic over end coils of the wound magnet wires have a metallic layer on them, such as by being metallized. The end domes can be formed with features which are also metallized. The thermally conductive plastic can have a phase change additive in it. The magnet wires can have a layer of heat activated adhesive that is activated when the plastic is molded. Slots in the lamination stack can include slot liners formed of thermally conductive plastic. A fan can be formed when the thermally conductive plastic is molded to encapsulate the magnet wires.
