phase asynchronous motor”of the national standard GB/T 10322012,a set of test and analysis system of threephase AC motor was designed by the advanced language C#. Firstly, the performance test and characteristic curves of the threephase asynchronous motor were given. The paper analyzed the principle of least squares and its realationship with characteristic curves of motor; Secondly, the general design of the system and the test flow of the motor were given; Then, the function of the system was illustrated by taking the noload test of a certain type of motor as an example. Finally,the actual operation showed that the system met the design specifications and requirements and improves the work efficiency
