Abstract: Aiming at the problems that the traditional motor testing system has the limitation of long time-consuming,tedious process and low precision,a kind of testing system was investigated with special functions of two-layer permanent magnet cylinder linear motor. A motor efficiency experiment was carried out to get the signals of velocity,force and voltage. The signals were uploaded by data acquisition device and data transmission device. LabVIEW was established as software development platform,to keep track of real-time signals and to research virtual instrument technology in the application of motor testing system. The experimental results indicate that the efficiency is 93.01% when the motor velocity is 350 mm/s,the acceleration is 7 000 mm/s2 and the resistance is 196 Ω. The testing system which has high reliability and measuring precision provides an important basis for the new style motor testing system.
Key words: two-layer permanent magent linear motor; testing system; data acquisition device; LabVIEW
