Design and Realization for Series AC Servo Motor Test System

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.
