Abstract
The rise in energy costs and growing environmental concerns are driving investments in energy-saving technologies, particularly in the maritime industry, including fishing, marine operations, and shipbuilding. Shaft generators are highly favored for their ease of installation, cost-effectiveness, reliability, and low maintenance costs as an energy production system of choice. These systems are well-suited to meet the energy demands of military vessels. As current energy costs and environmental pressures continue to escalate, shaft generators are recognized as pivotal technologies supporting energy conservation efforts. This study provides a comprehensive comparative analysis of the design and energy efficiency of two different shaft generator models employed on military ships. Using ANYSYS/Maxwell for design and analysis, the study evaluates power, torque, and efficiency across both models. The results emphasize that the efficiency of a shaft generator depends mainly on two factors: the number of motor poles and the operating frequency of the system. Moreover, the efficiency tends to decrease as the number of motor poles increases, but it improves as the system frequency rises.
