An approach helpful when developing an optimized construction of a 6/4
type switched reluctance motor (SRM) is described in the paper. The
analytical modeling procedure, based on the reluctance network method and
analytical solution of an ordinary differential equation, enables applying
a gradient optimization routine and better control of optimization
process. The model allows for estimation of the efficiency, torque, and
acoustic noise of the motor taking into account the magnetic non-linearity
and the control algorithm to keep a constant input power. A bicriterial
optimization routine has been applied to find optimal constructions.
Eleven geometric and winding parameters are supposed to be the
optimization quantities. Analyzed constructions – the initial one and the
optimized ones, were validated by means of FEM calculations. The proposed
approach can be employed in designing the SRM to be a drive motor in an
electrical vehicle, at least as a first attempt.
