Fast Torque Estimation of In-Wheel Parallel Flux Switching Machines for Hybrid Trucks

Abstract

Recently, parallel flux switching machines (PFSM) have come forward as a promising candidate for hybrid and electrical truck applications due to their high power density. Torque calculations, i.e cogging and electromagnetic, are important features of these machines. However, they require a finite element model (FEM) with a long simulation time, especially for transient analyses. This paper explains how the simulation time can be minimized by employing a torque superposition principle.
