摘要
介绍电刷宽度对电抗电势的影响， 如何有效地增加电刷宽度， 同时介绍了直流电机的无火花换向曲线，
This paper introduces the influence of the electric brush width on the reactance electromotance.rlow to make the electric brush wide effectively is described.No sparking commutation curve of the direct current machine is also introduced.We should pay more attention to the problems when the reactance electro motance is reduced and the electric brush width is enlarged.
