Abstract

While numerical analysis techniques, such as a finite element analysis and boundary element analysis, have been presented as an accurate tool for design and simulation of Switched Reluctance Motors, they do not give any method of a systematic design procedure with a minimum computational effort. Besides, They have not introduced any matching with the conventional design approaches used in classical machine design. This paper presents a systematic design procedure based on magnetic circuit analysis and standard proportion among motor parts to determine the motor dimensions. The proposed procedure is generally structured to run on personal computers to design and simulate any permissible specifications, in a few minutes. It has been shown that, for fast and more traditional design, no numerical techniques are needed, since the magnetic circuit analysis is more simple and complete in itself. The proposed program is not limited only to the motor iron and copper dimensions, but also estimates many of performance indices such as output power density, generalized power factor, losses and efficiency.
