Development of a Performance Test Platform of Direct-Drive Servo Valve Linear Force Motor

In order to test the performance of liner force motor accurately, reliably as well as conveniently, with function as key element in direct-drive servo system, the platform for their characteristics test was developed, according to their structural features and performance characteristics with combination of sensor technology. Automatic and precise test for the profermance of liner force motor was realized. Practical test and analysis results of a specific liner force motor inidicate that, the system is convenient and safe to operate, and has advantages of stable as well as reliable test rasults. Accordingly, it can be suitable for the characteristics test of common linear motor.
