Switched reluctance motor drive system (SRD) is to appear in the 1980s, a new type of variable speed drive system. It is with the microelectronics technology, control technology, power electronics and modern computer technology and development. The system mainly consists biconvex pole reluctance motors, power converters, position sensors and controls four-part composition, the structure is simple and rugged, high reliability, wide speed range, with higher efficiency in the entire speed range, and easy to manufacture into a sealed structure and water-proof, dust-proof, explosion-proof structure, suitable for harsh environment applications, and does not require frequent maintenance. Its products have been widely used in various fields of electric vehicle drive systems, home appliances, aviation industry, has become one of the hot topics of the contemporary electric drive. Industrialized production of switched reluctance motor drive system did not form scale, mainly due to torque ripple and noise caused by its own structure, running fever and serious, the other due to the presence of the position sensor, not only increases system cost and complexity, and reduces the the SRD system of reliability. To solve these problems, the study of switched reluctance motor mainly in two aspects: on the one hand is the design and optimization of the motor body, analysis of the impact of structural parameters of the switched reluctance motor motor performance, Switched Reluctance Motor to establish a precise and reasonable non-linear model, the formation of a switched reluctance motor design theory; the other hand, motor control, to take appropriate control strategy, the choice of reasonable power conversion circuit and the switching frequency design method, which eventually formed a complete set of lower noise and vibration and torque ripple control strategy. This paper analyzes the structure and composition of the switched reluctance motor drive system, summarizes the principle and structure characteristics of a switched reluctance motor running, some of the parameters in the design process of switched reluctance motor drive system operating characteristics, as well as the motor body calculation and select analysis the impact of the choice of these parameters for the performance of switched reluctance motor running, the researchers switched reluctance motor linear model typical quasi-linear model, the nonlinear model and the switched reluctance motor control, which is the analysis of the motor good theoretical basis. Then this article as a research tool to electromagnetic field analysis software the ANSOFT / MAXWELL and Rxmpt of a switched reluctance motor prototype expand computing, the use of two-dimensional finite element method and the three-dimensional finite element method simulation model, given the material properties, set the boundary conditions and excitation source prototype magnetic field calculated by Simulation, the prototype of the magnetic field distribution characteristic curve provides a method for the design and analysis of switched reluctance motor. Finally, I would fieldwork switched reluctance motor parts processing production, as well as the final assembly of the actual production process, experimental testing and motor testing experimental station switched reluctance motor drive system on the existing models, collected Switched Reluctance the motor waveform test data, combined with the theory of the motor as well as software simulation of switched reluctance motor measured waveform analysis, in order to choose a more rational design parameters to improve the performance of the motor running.
