Description
Summary:This paper presents a mathematical description of the electromechanical energy converters with permanent magnets. Unlike well-known mathematical models the mathematical description is obtained by the joint solution of Maxwell and Fourier equations. This allows to determine the geometric dimensions of the active part of electromechanical energy converters taking into account thermal and electromagnetic processes on the stage of the design calculations. Finite element method is used for the final calculations of the full geometry of electromechanical energy converters. Computer simulation and experimental study of electric machines with high-coercivity permanent magnets were investigated to evaluate the effectiveness of the obtained results. The results of experimental studies have been compared with mathematical model and its high accuracy was obtained.
