Accurate and Fast model for single Rotor Double Stator Interior Permanent Magnet Brushless Synchronous Machine with Spoke-Type structure at no-Load

Abstract

In this paper a 2-dimensional model by solving partial differential equations for single Rotor Double Stator Interior Permanent Magnet Brushless Synchronous Machine with Spoke-Type structure (SRDSIPMBSMWSTS) is formulated to predict flux density in air-gaps at only no load. After extracting relations are governing in each domain (magnetic potential vector and magnetic field intensity), boundary conditions between each two domain that are in adjacent to each other are applied to determine unknown coefficients. Output results are compared to finite element analysis (FEA) yield from Maxwell software to validate this fast and accurate model.
