The first purpose of this paper is to clarify statistically which factors affect the outage of induction motor coils and which factors do not affect the outage. The second purpose of this paper is to find statistically how to decide design factors to reduce the outage of coils quantitatively. Up to now such result has hardly been reported. We statistically analyzed 128 outage of coils from 16 kinds of induction motors in the last eight years and tried to obtain a design guideline for induction motor coils. Six design factors were considered. They are (1)protection of induction motor frame, (2)winding method of the coils, (3)temperature rise in the coils, (4)space factor of coils in the stator slot. (5)an index number of coil damage and (6)an index number of stress on the coil ends. As a result of the analysis of variance for (1)-(4),the difference is not significant, but for (5) and (6) there is a 1% level of significance in its difference. The outage decreases by about 10% as (5) or (6) decreases by 10%. Thus coil outage can be dealt quantitatively in design which has been considered only qualitatively until now. Better optimum design of induction motors can be performed by using these index numbers as design guidelines with characteristic, economical and manufacturing factors. |
