Abstract(in English) | Commutation analysis is important for improving performance reliability in DC machines. Existent commutation analysis methods only satisfy to solve No-Spark-Zone. However those methods do not satisfy to estimate spark energy level, which directly determine the performance reliability of DC machines. In this paper, the commutation curve measured using commutation tester and commutation curve calculated in solving first order differential equation named "commutation equation", using numerical integration are compared. As a result of this study, it is clarified that application of non-linear brush contact voltage-current characteristic to the commutation equation is necessary for such accurate analysis as is for estimating spark number in JEC-2120. |
