Abstract: A rotor includes: a shaft; a core around the shaft; at least one end ring connected to rotor bars that are at least partially enclosed in the core; and means for balancing the end ring around the shaft in a pre-balancing spinning process. A method includes: assembling rotor bars so that they are at least partially enclosed in a core of a rotor; connecting an end ring to ends of the rotor bars; inserting a shaft into the core; step for balancing the end ring around the shaft in a pre-balancing spinning process that involves spinning the rotor; and spinning the rotor in the pre-balancing spinning process.

Abstract: A rotor assembly and a method for fabricating the same are provided in which a pair of end caps, positioned at either end of the stack of laminated discs, are fusion welded to the rotor bars using an electron beam welder, thereby yielding improved electrical and mechanical characteristics in a low weight assembly.

Abstract: A dual-winding layer arrangement for a three-phase, four pole motor is provided.

Abstract: A method of manufacturing a triple-winding layer arrangement for a three-phase, four pole motor is provided.

Abstract: A method of manufacturing a three-phase, four pole motor is provided utilizing a dual-layer winding insertion technique. The first and second winding layers are each comprised of the coil groups for six individual poles, two per phase. Within each layer, the two poles per phase are members of a pole pair. In one configuration, each winding layer is comprised of six concentric coil groups in which there is no coil overlap; alternately, each coil group may be comprised of five coils with either the first or second or both outermost coils of each group being double-turn coils; alternately, each coil group may be comprised of five coils with no coil doubling, although there are overlapping coils from different coil groups; alternately, each coil group may be comprised of five coils with no coil doubling and no overlap between different coil groups, although the coils within each coil group are completely lap wound.
