Analysis of SPMSMs with Outer Rotor Configuration by Analytical Model and Finite Element Technique

In this study, a surface mounted-permanent magnet synchronous motor (SPMSM) with outer rotor configuration applied to the fields of industry and electric drive is proposed by an association between the analytical model and finite element technique.Firstly, the methodology involves a detailed development of the analytical calculation to compute crucial parameters for the SPMSM.Next, a finite element technique is proposed to validate the analytical parameters and simulate various aspects such as the magnetic flux density, output torque, cogging torque, torque ripple, back electromotive force, flux linkage and temperature rise.The developed methods are tested and validated on a practical problem involving a 7.5kW SPMSM with outer rotor type.
