IMPROVEMENT OF THE TERMINAL CHARACTERISTICS OF A SLIGHTLY MODIFIED DC MACHINE WITH AN ELECTRONICALLY ASSISTED COMMUTATION

In [10], we have presented a new d.c. machine arrangement which is especially designed to operate with an electronically assisted commutation. The experiment has succeeded and the modified d.c. machine operates at a power equal to 1.4 times its initial nominal power without any spark under brushes. We present, in this paper, the obtained results.
