Abstract :
This paper investigates the influence of physical size of a switched reluctance motor on its output performance. Three four-phase switched reluctance motors with different dimensions and power ratings are used for comparison. The magnetic characteristics of each motor are described using a 2D finite element method. Field solutions from finite element calculation and analysis combined with the output equation are processed to give the energy conversion loop, ψ~i trajectory, for each motor. The comparison of the output performance and ψ~i loop for each motor provides the basis for the discussion on the relationship of output performance of a switched reluctance motor to its physical size
