Abstract: This paper introduced a method of series AC servo motor test system design and realization. Test system adopted the three-phase 400Hz digital voltage meter and the alternating current phase sequence detection circuit, designed the simple and practical phase detection circuit. For three-phase AC phase detection circuit, combined with the amplitude and phase sequence detection was achieved by servo motor back-EMF Detection and display status. The practical application results show that, the design of back-EMF test system has the economy, stability and practicability, can fully satisfy the series AC servo motor production line test requirements.
