To solve the problem of resistance jump in three - phase winding of servo electromotor during maintenance of shipboard satellite communications station, the principles of permanent magnet synchronous servo motor and transmission chain of antenna are analyzed thoroughly, and combining with the basic circuit of digital multimeter, a simplified model is proposed for measuring the resistance of three - phase winding using a digital muhimeter. The electromagnetic principle and the test at sea indicate the reason of resistance jump, based on which the influence to the system can be concluded and the solution is proposed, which solves the problem effectively.
