Abstract :
Three-phase capacitor motor with main winding and auxiliary winding vertically arranged in space can effectively weaken the harmonic MMF (magnetic motive force), and raise efficiency and power factor. In this paper, performance of new three-phase capacitor motor in frequency control system is analyzed. Through the contrast experiment between the new three-phase capacitor motor and three-phase induction motor, it has an in-depth research on torque characteristic, current characteristic and power factor. And then it shows the superiority of the new three-phase capacitor motor according to experimental data.
