It would be quite interesting to have an explanation as to what particular types of motor failings each of the test types are detecting, and some explanation about the mechanism o0f detection. The failure modes that I am aware of are short circuits and leakage to the frame, short circuited turns, and winding opens. Leakage is not that hard to detect, shorted turns would be easily found by the impulse, or inductive ringing tests, and winding opens are easily detected with an ohm meter. Locating the actual fault in order to repair it is a lot more challenging though. Then there are other faults, such as bearing noise and loss of balance, which are also problems but sa bigger challenge to detect electrically.
I think the big point that resonanted to me throughout this article was to design products that are user-friendly. While the selected product was not at the high end in its market segment, one of the most important selling features was good user-friendliness.
There is no doubt that the recent developments in technology will enable an efficient winding and motor testing process. However, most customers will have no idea of the details of the entire process. This calls for a need to ensure customer satisfaction and employ the use of professionals in ensuring an efficient winding process.
