Resumo(s)
This paper presents a set of similarity laws
appropriate for low speed switched reluctance machines design.
Design methodologies of switched reluctance machines for low
speed applications are generally oriented towards the choice of
suitable combinations of stator and rotor poles in regular
topologies. The proposed similarity laws provide an easy-to-use
and robust methodology to compare different magnetic
topologies, regular or non-regular, and have the capability to
incorporate thermal and magnetic saturation phenomena by
introducing constraints. With the assistance of finite-element
analysis the issues surrounding the design of low speed SR multimachines
topologies are discussed, leading into consideration of
modular non-regular topologies. Using similarity laws, the
modular topology is compared with a regular switched
reluctance machine. The comparison results point out the
reduction of copper losses of the modular topology over the
regular topology. This paper extends previous discussions of
switched machine design into a more general context.
