Nonlinear Modelling Approach for Linear Switched Reluctance Motor and its Validation by Two Dimensional FEA
Keywords:
Actuator, analytical model, computer simulation, electromagnetic forceAbstract
This paper exposes two procedures in order to develop a refined analytical model which describes the behaviour of a linear switched reluctance motor. The first approach is based on the flux linkage and the second on the inductance, both versus position and current. Taking into account the non-linearity of the magnetic circuit, models are expressed by either Fourier series or polynomials where the only first three components are considered. Results of these analytical approaches are compared with those obtained using finite element methods (FEM) where a good agreement is observed.
