Fabrication and Assembly Method for Synchronous Reluctance Machines

In this paper, a comprehensive manufacturing and assembly process of synchronous reluctance machines (SynRMs) is presented. One stator and two transversally laminated anisotropic (TLA) SynRM rotors are manufactured using cold-roll nongrain-oriented steel. To enhance the performance of the designed SynRM, a TLA segmented SynRM rotor is fabricated using cold-roll grain-oriented steel. The application of nonconventional photochemical machining to produce machine laminations is presented. Different stages of manufacturing, stator and rotor assembly techniques, rotor balancing procedure as well as specialized components used at various stages of the process are described. Performance characteristics such as static torque-angle curves are obtained experimentally to verify the accuracy of design, manufacturing, and assembly.
