Considerations on Magnetic Circuit Model of Linear Parametric Motor Using Four Legs of Laminated Iron Core

We propose a magnetic circuit model of a linear parametric motor using four legs of laminated iron core and calculate the fluxes and static thrust of the linear motor under two-phase exciting conditions. The calculated values based on the magnetic circuit model agree well with the experimental values in the wide region of the phase difference between the two supplied voltages. The magnetic circuit model presented here is considered to be useful for the analysis of the linear motor under parametric oscillation.
