Design and Comparative Analysis of Halbach array and Surface mounted magnetic pole Dual rotor De-Coupled Stator Six-Phase Permanent Magnet Synchronous Generator for Wind power Application

Abstract

The technological development provokes the researchers to research in the field of the dual-port, multi-phase generating systems and machines with fine arrangement of magnetic poles for Higher Power Density (HPD) and reliable operation. Due to this, the authors opted for Dual Rotor Halbach Array Magnetic Pole De-Coupled Stator Six-Phase PMSG (DRHBAMPDCSSP-PMSG) and Dual Rotor Surface Mounted Magnetic Pole De-Coupled Stator Six-Phase PMSG (DRSMMPDCSSP-PMSG) for their investigation. The key motive of this research paper is concerned with the investigation of design and comparative analysis of Halbach array and surface mounted magnetic pole dual rotor de-coupled stator six phase permanent magnet synchronous generator for wind power application. To fulfill this objective, the Finite Element Method (FEM) is opted because of its high accuracy. Using transient and magnetostatic methods, the assessment of electromagnetic performances like Generated Voltage (GV), percentage (%) THD, electro-magnetic torque vs time, % torque ripple etc are investigated for both proposed generators.
