Design and thermal investigation of a dual rotor de-coupled stator multi-phase permanent magnet synchronous generator for wind power application

Abstract

This paper reveals the design and thermal investigation of a Dual Rotor De-Coupled Stator Multi-phase Permanent Magnet Synchronous Generator (DRDCSMP-PMSG) for wind power application. The motive of thermal investigation is to employ it for the optimal selection of various materials required for the advancement of DRDCSMP-PMSG. The Lumped Element Network Model Method (LENMM) and Finite Element Method (FEM) are used for the thermal investigation. The conclusion of the two methods exhibit good agreement. The Lumped Element Network Model (LENM) in the paper has sixteen nodes corresponding to critical parts to compute distribution of temperature in different sections of the DRDCSMP-PMSG like shaft, inner stator yoke, permanent magnet, outer stator yoke etc. Although, the accuracy of Finite element thermal model is more than the lumped element network thermal model, it takes considerable time for the improvement in machine design and simulation process. © 2020 IEEE.
