A Generalized Methodology for Health Index Calculation for PMSM Drive System

This paper mainly discussed the motor and converters' health indexing. The health index gives the idea about the present condition or age compared to the healthy system. The objective of this paper is to present the health index (HI) calculation method for PMSM and converters to identify the real-time health of the device. There are many articles available for the transformer health index calculation, and some of the papers discuss about the power system health index calculation. Also, we have many ways to calculate the health index, like weight-scoring, fuzzy-logic-based, neural networks, and AI/ML-based methods. The weight-scoring method is simple to understand as well as for computation. Therefore, in this paper, we have developed the concept of the weight-scoring method to calculate the health index for the combined system of PMSM and converter as a drive. Therefore, based on the condition monitoring (CM) parameters received from the system, are used to calculate the health index. The result of the health index represents the degradation or age of the system/equipment.
