中文摘要：

通过单片机控制步进电机的旋转和电磁铁的吸合，对电机电枢进行试验和检测，并通过单片机与智能仪器的通信将所测量的结果进行存储、显示和比较判断，并打印结果，实现了电枢参数检测的自动化，提高了电机检测质量。

英文摘要：

A new kind of intelligent instrument, which detects armature parameters automatically, is developed. This equipment can test the armature of motors through controlling rotation of the step motor and controlling open and close of the electromagnet by a single chip. It can store, display and compare the detected results and improve quality of checking and repairing motors greatly.
