Abstract:

This article discusses the difficult problem of measuring motor parameters,Based on this proposed a "dummy load" in the form of three-phase asynchronous motor test system.This system does not have to drive the actual mechanical load.Only through the static test data and load test.The collected short circuit test phase voltage, phase current and other data.Can analyze the importance of the three-phase asynchronous motor performance parameters by the Analytic circle diagram method and Virtual Instrument Software.Such technical solution not only improves the accuracy and precision of the data processing,but also reduces operator workload.And compared to traditional measurement techniques,the motor running and the cost of the motor test saves a power consumed.Make intelligent measurement and analysis system more "green".

Key words: Asynchronous motor, intelligent measurement, Analytic circle diagram method
