【Abstract】 The combination of computer software and the sensing technology has become a new way of development of motor automatic test system in recent years. What’s more, the rapid development of modern electronic technology provides a possibility to using the new test method to improve precision and speed of the motor characteristics test. And it also further promotes the development of motor testing technology. Under the background of the development, this paper proposed a modularity mechanical characteristic test system for a single AC servo permanent magnet synchronous motor testing based on Lab VIEW software development platform. The test system use PC as main control unit and use PCI data acquisition card to collect the data. This paper complete the structures designing of the system in Lab VIEW software development platform. The main contents include:Firstly, analysis and design of testing system overall scheme, Mainly including the measurement principles of motor speed and torque, and the curve drawing method. Analysis and design the overall scheme of hardware and software platform.Secondly, The hardware platform design, mainly including the design of the mechanical transmission structure and test platform support.Thirdly, design and debug the test system software program in the LabVIEW software platform. Mainly include that main interface design and motor revolving speed and magnetic powder brake control program design. In addition, it also including the program designing of data acquisiting, processing, display and saving.Fourthly, the test platform installation and debugging, and using the test platform of ac servo permanent magnet synchronous motor to complete revolving speed, torque test experiment.
