2-D analytical modelling of novel consequent pole linear permanent magnet flux switching machine

In this paper, a novel Consequent Pole Linear Permanent Magnet Flux Switching Machine (CPLPMFSM) with flux bridges and flux barriers is proposed and compared with existing conventional Linear Permanent Magnet Flux Switching Machine (LPMFSM). Proposed machine successfully curtailed demerits of conventional LPMFSM such as high flux leakage, thrust force ripples, peak to peak detent force and Permanent Magnet usage. After electromagnetic analysis utilizing Finite Element Analysis (FEA) software package, expressions combining Lumped Parametric Magnetic Equivalent Circuits, vector potential governed by Laplace Equations, and Maxwell Stress Tensor method are used to develop 2-D analytical model for open circuit flux linkages, no-load and on-load Magnetic Flux Density, detent force and thrust force. Results of 2-D analytical models are validated with corresponding FEA utilizing JMAG Commercial FEA Package v. 18.1 and show good agreement with an accuracy of ~ 97%. Authors are confident to recommend developed 2-D analytical models for initial design of CPLPMFSM.
