Introduction. Increasing the energy efficiency of electric generators is a pressing task for various areas of energy, in particular for autonomous systems and transport. Synchronous-reactive generators (SRGs) are becoming increasingly widespread due to their simple design, absence of magnets and mechanical contacts, and high reliability. The task of the proposed work is to study the influence of the design of the double winding of the stator of a SRG on its energy characteristics, determine the optimal parameters of the mutual arrangement of the windings, and develop recommendations for increasing the generator efficiency. Goal. Analysis of the influence of the design of the double winding of the stator of a SRG on the output energy characteristics and determine recommendations when designing this type of electrical machines. Methodology. The analysis was carried out using numerical modeling by the finite element method in the ANSYS Maxwell environment. Various options for the mutual arrangement of the main and excitation windings in the generator stator were considered. Results. The influence of the single-layer and double-layer winding design on the output characteristics of the generator was studied. It was found that a two-layer arrangement with a phase shift of 2 slots provides minimal torque ripple, improves the stability of the generator operation and helps to increase the efficiency to 92.5 %. Scientific novelty. For the first time, the effect of the phase shift of the windings on electromagnetic processes in the SRG has been studied in detail, which allows optimizing its design and improving operational performance. Practical value. The results can be used in the design of new generators with improved characteristics for use in wind power, diesel generator sets and autonomous electrical systems.
