Since a laminated core parametric induction motor has a planar structure, there is a possibility of using mass production to reduce costs. In past work, we calculated the behavior characteristics of an orthogonal-core-type parametric induction motor in a locked rotor, using the reluctance network analytical model, and the analytical results showed good agreement with the experimental ones. In this paper, we examine the validity of applying the reluctance network method to the analysis of a laminated-core parametric induction motor while the rotor is driving.
