A Study on the Synchronous Reluctance Motor Design for High Torque by Using RSM

Recently, electric power consumption has increased rapidly owing to the development of electric devices, and thus environmental problems such as global warming have come to the fore. Therefore, developed and developing countries are preparing various measures to prevent global warming. Minimum energy performance standards (MEPS) are one of the representative measures. MEPS is an efficiency regulation for induction motors that limits the minimum efficiency with regard to the power of the induction motors, in order to save energy. Studies have been conducted on induction motors to improve the efficiency and to satisfy MEPS. However, It is very difficult to satisfy the efficiency of induction motor for MEPS. Therefore, synchronous reluctance motors (SynRMs) are actively being studied to replace induction motors. In this paper, a SynRM is designed using a Kw-map. Moreover, to improve the output characteristics, the rib thickness of the SynRM is optimized using the response surface method. Finally, the validity of the design method, proposed in this paper is verified with a real test using the prototype.This work was supported in part by the Korea Institute of Energy Technology Evaluation and Planning, in part by the Ministry of Trade, Industry and Energy of the Republic of Korea under Grant 20162010104100, and in part by the National Research Foundation of Korea funded by the Korea government (Ministry of Science, ICT, and Future Planning) under Grant 2016R1A2A1A05005392
