Report of Large Motor Reliability Survey of Industrial and Commercial Installations: Part 3

Results of a survey conducted in 1982 of the reliability of large motors have been presented and published in two parts [1], [2]. These results have generated numerous questions and comments and, consequently, the need to further analyze the data of the survey was recognized. Part I presents general results based on categories of motor types and applications specifically requested in the survey questionnaire. Part 2 combines various categories and addresses some questions resulting from Part 1. Part 3 of the survey results is presented here to address new questions and comments and to add more specific analyses of areas not yet explored. These results, along with Parts 1 and 2, provide the complete complement of analysis to date.
