Design of Surface-mounted Permanent Magnet Synchronous Motor using Electromagnetic and Thermal Analysis

다국어 초록 (Multilingual Abstract)

This paper proposes a design method of the surface-mounted permanent magnet synchronous motor using electromagnetic and thermal analysis. Since the electromagnetic and thermal fields are related, the permanent magnet synchronous motor should be considered not only in terms of the power density but also the thermal characteristics. The analytic method was used to investigate the power density of the concentrated winding model using the same number of poles. In the thermal design process, the analytic prediction was carried out by using the electromagnetic and thermal analysis called the lumped parameter thermal network (LPTN). The optimized geometry and losses which were calculated by the electromagnetic finite-element analysis were considered in the LPTN. As a result, an improved model was designed with superior power density and thermal characteristics to the prototype. Finally, the experiments were conducted to verify the validity of the design process and results.
