dc motor
(OP)
We have a Burgmann(cir1901)DC motor it has the normal two sets of field windings and comutator.It also has a separate comutator on the other end of the shaft.Can any one tell me why and how to use it. The motor is driving a lorry of the same age.There is also the normal starting resistors and contactor to switch them out.So it can run in series or compound.So why the extra com?
