Split ring commutator keeps the current flowing the same direction in the motor otherwise it would keep turning direction. This means that current is now flowing away from us through side X (whereas previously it was flowing towards us). When the field line argument is applied to transformers the explanation falls far short of convincing; again, the sign of a good transformer is that the magnetic flux is confined to the core, there is even a non-magnetic, non-conductive, gap (in the form of insulation) between the core and the windings. DC generators are also not as reliable due to sparking and wear across split ring commutators. The ring is split into two or more parts. get rotational energy O-Yeah! The current to the coil needs to be stopped at this point, because the FLHR forces acting at this moment would tend to hold the coil stationary in a vertical position. and do not touch each other.
