Abstract :
The paper discusses developments, and practical implementation of a novel digital signal processor (DSP) based system for the online real time monitoring of performance and parameter determination of three-phase induction motors. A software based algorithm is used to measure the performance and calculate the parameters of the three-phase induction motor in real-time, without the need to connect a mechanical load or drive to the machine´s rotor shaft. The new algorithm takes into account the machine parameter variations due to changes in electric supply, skin effect, mechanical load and any fault in the overall system, so the system can be used for condition monitoring of any electrical drive system and can be permanently or temporarily connected to such a system for diagnosis
