The research on brittleness source identification of electric machine system

Brittleness source of electric machine system is the element of rising brittleness motivated. Brittleness source identification is the work of finding every brittle source. At first, build model of electric machine system, based on direct current tide, all branch currents can be solved quickly. Break off every branch in turn. Use distributing factor method to obtain the other branch currents by breaking a branch current. If the other branch current exceeds the 20% rating current, then it breaks. This will lead to the refresh distribution, until all branch breaks, namely the brittleness being motivated, or until the other branch currents all satisfy the restriction condition. Thus all branches which lead brittleness to be motivated are the brittle source of electric machine system. Through analyzing a three generatrixs system, obtain that (2), (3) and (4) is the brittle source.
