Research and Development of Intelligent Motor Test System

This paper presented an intelligent motor test system in order to adapt the development trend of larger data scale and more complicated acquisition environment, and solve the low efficiency problem of motor testing device. It described the scheme of computer automatic data acquisition and processing system, application program structure and distributed network group control strategy of the intelligent motor testing system. The network group control system performes automatic switching and automatic controlling under various units running conditions in motor type testing. The paper also described in detail the equivalent circuit algorithm for motor working characteristics calculation and the non-linear LSM data fitting method for experiment curve. The system took full advantage of hybrid programming technology in interface developing, and of Period Tracking Technology which could solve the problems of measurement errors and low efficiency. It had been successfully applied in several motor manufactories.
