This paper presents a new reluctance network model developed in aim to design and optimize the linear switched reluctance motor. The developed reluctance network model is verified using finite element method. This reluctance network model takes an account the saturation of the ferromagnetic parts of the actuator. Also, the dispersion flux is modeled with a particular reluctance. Consequently, the reluctance network model gives precise results of the flux and the force. On the other hand, the important interests of the proposed reluctance network model is that this model can be coupled with other tools in aim to optimize the linear machine.
