Electromagnetic design of ultra-high efficiency permanent magnet synchronous motor for compressor

Abstract: Compressor, as a kind of driven fluid machinery, is a kind of general mechanical equipment that has a close relationship with various fields of industry and life and plays a very important role. It can increase the capacity of gas and overcome the resistance of air flow to achieve the purpose of piping gas and increasing gas pressure. Compressors are used in a wide range of applications, including military and civilian dual-use, industrial and agricultural two industries and other production areas, such as defense, military, machinery, chemicals, petroleum, mining, transportation and agriculture. Therefore, the consumption of compressors is very different. To reduce the energy consumption of compressors and achieve high efficiency and energy saving has become an urgent problem for many scientific research institutes and enterprises. Relative to other motors, the high strength index, good starting performance, and high efficiency at light load are the outstanding advantages of permanent magnet synchronous motors, and it is the development trend of compressor motors. This paper briefly introduces the development trend and research hotspot of permanent magnet motor for compressors. At the same time, it describes the basic principle structure and control method of permanent magnet synchronous motor. Under this principle, this article is a ultra-efficient for a 22KW/3000rpm.. The winding parameters, the length of the iron core, the rotor stator punching, the magnetic circuit structure of the rotor, and the design size of the magnetic steel are given a definite design. The simulation calculation is based on Ansoft Maxwell, and finally the original The manual calculation parameters are compared with the simulation calculation parameters to check the results.
