| Abstract |
In addition to the IEEE Standard Test Procedure for Induction Motors (IM), several advanced methods have been presented to achieve higher accuracy on parameters estimation. Some of them allow to estimate with high precision only a specific parameter, while others improve the parameters estimation at the price of high computational efforts and time due to finite elements analysis or the use of recursive algorithms.
After a survey of the main typologies adopted to estimate the electrical parameters in IMs, that highlights the main advantages and drawbacks of each category, this paper presents a novel procedure that can be adopted as parameters estimation. According to the proposed method the motor parameters are calculated through locked-rotor tests performed as the motor is fed by a standard inverter, by exploiting simple relationships which do not increase the computation effort. Simulation and experimental results have been performed on different motors and, comparing the proposed approach to other methods, they have confirmed its validity.
