Design and Performance Characteristics of Dual-Rotor Magnetically Decoupled Stator Five-Phase Permanent Magnet Synchronous Generator for Wind Power Applications

The prime focus of this paper is the performance evaluation of a Dual-rotor magnetically decoupled stator five-phase permanent magnet synchronous generator (DRMDCSFP-PMSG) for wind power application. The proposed generator poses essential benefits like high power density, high efficiency, light in weight, high fault tolerant capability, and high reliability. The two sets of five-phase windings of decoupled stators of proposed generator confirm the high reliability and high degree of fault tolerance capability of generator. The finite element method (FEM) is used to evaluate the performance of the generator due to its accuracy. The magnetostatic and transient mode of analysis are considered for the optimal designing parameters of the machine. The following performance parameters are investigated for the DRMDCSFP-PMSG—electromotive force (EMF), percentage (%) total harmonic distortion (THD), generated EMF versus speed, electromagnetic torque, % ripple in the torque, terminal voltage–current characteristic, and % efficiency-current characteristics.
