Commutation parameters of 700kW pulsating traction motors at high speed with minimum field weakening are analysed. It is found that the ac unbalanc- ed electromotive force under such conditions is much larger than that under normal conditions. Therefore, an inductive shunt should be inserted in the adjustable shunt circuit to improve commutation performance at high speed,so as to meet the locomotive running requirement at high speed.The effect of different reactances on decreasing ac unbalanced electromotive...

Commutation parameters of 700kW pulsating traction motors at high speed with minimum field weakening are analysed. It is found that the ac unbalanc- ed electromotive force under such conditions is much larger than that under normal conditions. Therefore, an inductive shunt should be inserted in the adjustable shunt circuit to improve commutation performance at high speed,so as to meet the locomotive running requirement at high speed.The effect of different reactances on decreasing ac unbalanced electromotive force is also analysed. This paper describes several structuralmodifications for improving commutation stability and reducing the possible sparking and flashover.

The opening air-gaps with circular main pole arc are usually used to improve the potential curve of commutator on non-compensable d.c.traction motors.This paper puts forward a set of formulas from the main pole arc formed by two segments of eccentric circular arc.By means of these formulas,designers can obtain a large number of more ideal gaps for choice.The eccentric gap,which is widely used now,is the special example and is not the best one. Besides,the paper advances a new design method and programme which are opposite from tranditional i.e.,a method of designing the gap from given potential curve.Therefore we may obtain the most ideal gap.
