This method is … WebA shunt field (and any series resistor used for adjustment) may be directly connected across the armature terminals in parallel with the load. Where the machine has a series compounding winding, the field may be connected at the armature side (short shunt) or load side (long shunt). The different connections give different voltage regulation ... nerve and muscle damage
