[Abstract]:Switched reluctance motor (SRM) is a new type of special motor. Its speed regulation system has obvious advantages over the traditional AC and DC speed regulation system. Motor testing is to test and verify the motor indexes, to judge whether the motor meets the design index and whether it can meet the requirements of safe use. Virtual instrument testing system is a hardware and software as one of the equipment, application software is open, high flexibility, combined with computer hardware resources, broke through the limitations of traditional instruments, greatly improve the function of the instrument. In this paper, a switched reluctance motor test system based on virtual instrument is put forward, and how to realize the test of switched reluctance motor by virtual instrument, such as load characteristic, pulsation characteristic, and automatic testing of motor, is mainly studied in this paper. This paper focuses on the research and application of virtual instrument in the design of switched reluctance motor testing system. Firstly, according to the motor testing, virtual instrument research situation at home and abroad to carry on the study. The defects of modern motor testing system and the advantages of virtual instrument are analyzed. At the same time, the characteristics of switched reluctance motor (SRM) are analyzed according to the characteristics and control strategy of SRM, so as to prepare for the design of test system. On this basis, the overall analysis of the test system and hardware selection, and LabVIEW virtual instrument as the development environment of this paper. According to the torque ripple characteristic of switched reluctance motor and the load characteristic of non-sinusoidal motor, the related program is compiled and the test interface is established, and the auxiliary functions such as report generation, data storage and login interface are provided to facilitate the operation of the user. Ensure the safety of the system. On the basis of theoretical analysis and system design, this paper takes a 0.5kW three-phase 32-pole switched reluctance motor as the test object, adopts WT3000 high-precision power analyzer, DL750 oscillograph recorder and DAS-100A data analysis software as the standard. The precision of the test system is measured by load test and torque ripple test. The experimental results show that the test system meets the precision requirements and can be used in practical production.
