Permanent Magnet Generator with the Tooth-Coil Winding and Saturation Magnetization of the Magnetic Core

Abstract

This paper considers the advantages and disadvantages of using electric generators with high-coercivity permanent magnets and a tooth-coil winding as a power source in hybrid power plant systems. The requirements of such power generators are considered. In this paper, a special topology of an electric generator with high-coercivity permanent magnets with the use of an additional winding is proposed. The features of the proposed generator topology are shown and its mathematical description is given. For the study of electromagnetic processes, a computer simulation of the proposed generator was performed and the results of modeling were presented. To verify the calculated values of the generator and the results of computer simulation, an experimental study on a prototype of the proposed electric generator with high-coercive permanent magnets was carried out. The results of the experimental study showed high accuracy of computer simulation and numerical calculation.
