为实现电动机机械特性的自动化测试,提出了一种电动机机械特性自动测试方法,采用能提供均匀、稳定负载的磁粉制动器与可高速、高精采样的转矩转速传感器,搭建了系统硬件平台,利用Visual C++编写了配套测试软件,从而组成了基于PC的电动机机械特性自动测试系统,并以直流电动机为例给出了测试结果。试验结果表明,该系统可实现对电动机机械特性的高效、精确测试。

PC-based automatic test system for motor's mechanical characteristics

Aiming at realizing automatic test of motor＇s mechanical characteristics,an automatic test method was proposed,and a PC-based automatic test system was designed with the hardware platform and the testing software.The hardware platform was made up of a magnetic powder brake which could provide steady loading and a torque-speed sensor which could take sample quickly and precisely.And the testing software was designed with Visual C＋＋.Testing results were presented via example of direct current motor.The test results indicate that the system can make efficient and precise test of motor＇s mechanical characteristics.
