An investigation on residual life diagnosis system of low voltage rotating machines for elevator equipments was conducted in the purpose of predicting the insulation deterioration accidents. The algorism of presented diagnosis system follows the following process: analyze a deterioration grade based on non-breakdown data by an expert system developed before and being tried in the establishment places, estimate one more deterioration grade corresponding to the insulation breakdown time by a regression analysis on actual breakdown voltage (BDV) databases, and finally estimate a residual insulation life by a regression analysis between the deterioration grade and databases with the operation progress days. These databases were made as the results of insulation breakdown tests for 150 low voltage rotating machines removed from the various elevator operation places. This paper reports about the trial of the system that the residual insulation life is predicted with referring to the BDV databases correlated with the inputted non-breakdown data in the above process. The system performance is discussed in terms of the breakdown voltage inspection in detail.
