Abstract

Double Stator Hybrid Excitation Flux Switching Generator (DS-HEFSG) has attracted significant interest in power-generating research owing to its potential for improved performance and sustainability. This research examines the utilization of hybrid excitation to enhance the efficiency of a three-phase DS-HEFSG specifically engineered for low-speed power applications such as renewable energy systems like wind and tidal turbines. The innovative method presents a double stator hybrid configuration for a traditional double stator generator, with performance evaluation performed via 2D finite element simulations. The findings indicate that the DS-HEFSG surpasses traditional topologies, rendering it an optimal selection for this generator configuration. The proposed design significantly increases the 18.76% cogging torque value while the electromotive force increases by approximately 21.62%. The proposed design also decreases permanent magnet eddy-current losses by 24.33%. Enhanced performance is noted in electromagnetic torque, torque ripple, output power, and overall efficiency. These advancements contribute to energy savings and lower maintenance costs, reducing reliance on fossil fuels and supporting the transition to greener energy solutions. The proposed DS-HEFSG with hybrid excitation is a viable alternative for efficient low-speed power production.
