Investigations on changing inductance values on the operation of SynRM attached to pump system

The inductance profile of SynRM (synchronous reluctance machine) is obtained by different testing methods. This results in different inductance profiles. While operating an SynRM, these variations in inductance profile can cause disparities in the performance parameters when it is running at a particular speed. This paper presents a new method pertaining to the usage of inductance profiles obtained by different test methods, for a synchronous reluctance motor coupled to a pump load. This analysis depicts the impact of inductance profiles of the motor in estimating the operating state of SynRM driving pumps, while SynRM is affected by voltage dips. This, in turn, will be helpful in assessing the optimized values of motor performance indices.
