Abstract: Put forward a kind of test system based on virtual instrument to solve the problem that the traditional motor test system has the limitation of long time-consuming, tedious process and low precision and induction motor has the special performance in electric power steering system (short for EPS). The test system is developed using PC as main control unit based on PCI6052E board, LabVIEW as the soft developing platform. This paper introduced the hardware platform and software design in detail. The experiment shows that the test system is feasible. The test system has simple structure, high reliability and measuring precision. It provides an important basis for the induction motor test system in EPS.
