Switched reluctance motor speed control system SRD (SwitchedReluctanceDrive) is the latest generation of AC stepless speed regulation system developed after the frequency conversion speed regulation system and non-commutator motor speed control system. It has many advantages such as simple structure, firmness, low cost, reliable operation, flexible control and high operating efficiency. The transmission system composed of it has the advantages that AC and DC transmission systems do not have. This article mainly introduces the development and basic composition of the speed control system of the switched reluctance motor, analyzes the principle of the speed regulation of the switched reluctance motor, and elaborates its application fields and fields on the basis of its advantages and disadvantages.
The basic principle of a switched reluctance motor (SRM or SR motor) was first proposed in the 1940s, when researchers at the time believed that it was simple and feasible to use a sequential magnetic pull to rotate the motor. In 1842, Aberdeen and Davidson of the United Kingdom produced the original SRM model, but because of the backward technological conditions at the time, the operating characteristics of the motor were poor. Over the next 100 years, the development of switched reluctance motors has been slow. In 1975, research teams from two universities, Leeds University and Nottingha University in the United Kingdom, participated in the study of manufacturing battery-driven vehicle-driven equipment initiated by Chlorid and successfully developed the SRD for driving electric vehicles. In 1980, Lawrenson and colleagues from Leeds University summarized their research results and published the paper “Switched Reluctance Motorâ€, which marked that SR had been formally recognized internationally. In 1983, the British TASCDriv Company launched the first commercialized SRD-Oulton transmission (7.5kW, 1500r/min); in 1984, it introduced 4 to kW4 specifications of the series [1]. As a new type of speed control system with high performance and price, the introduction of SRD has attracted widespread attention from all walks of life. The United States, Canada and other countries competed for development and made great progress in system integration design, microcomputer application, motor electromagnetic analysis, power component application, and new structure development.
China's research on the speed control system of the switched reluctance motor started late, but it has a relatively high starting point. It can develop rapidly based on the experience of foreign countries. China's research and trial production of the switched reluctance motor speed control system started in the 1980s. The first Symposium on Switched Reluctance Motors was held in Nanjing in 1988. In 1992, the Switched Reluctance Motor Science Group was established under the leadership of the Small and Middle Electrical Machinery Committee of the China Electrotechnical Society to better advance the research work of the switched reluctance motor. Based on the experience of foreign countries, the research and development of the speed control system of the switched reluctance motor in China started late, but the starting point is relatively high. The research and development goals are basically concentrated on the more mature three-phase or four-phase control scheme. A group of colleges and universities and research institutes carried out this work. Some key universities and colleges recruited doctoral and master students with multiple issues of switched reluctance motor speed control systems, and achieved many results from basic theory to design and manufacturing techniques. With progress. Up to now, more than ten units have launched dozens of series of products with different performances and different uses. They are used in dozens of production machinery and vehicles in the textile, metallurgy, machinery, and transportation industries. Switched reluctance motor Speed ​​systems play a unique advantage in some machines.
