There some designs that could be little are just one field in dynamo, like the E3L used on vintage motorbikes. This type, dynamos are eccentric which to say that the armature does only not run throughout the center in diameter but also offset. That is because it just one field and pole shoe. That kind of design also use on early dynamos. There are such things as replacement field coils.
Some faults might occur with flexible leads which used in connecting the ends of coils with each other than into terminal box. The leads could replace if clean connection could made on coil without making damage on the insulation. If coil had burnt or a fault is with coil itself then possibly not making repair this kind of motor.
Rotary machines that is electrical would require the current to convey extracted the moving rotor, generally it means that sliding contacts slip rings or commutator. Those contact is the least reliable and most complex part of machine. That might also present the limit on maximum current the machine could handle. That reason when the machines should use the two set of windings that carry the least current.
For generators, current is much smaller than output current. The field accordingly is mounted on rotor then supplied using slip rings. Outputted current is then taken from stator, fully avoiding need for high current. In DC generators, that are generally now obsolete favor AC generators that has rectifiers, need for the commutation that commutators and brush gear could still require.
That usually would sound better in more voltage apply this is stronger magnetic equals to better transit responds which gives you more detail, those things can overheat though it a lot of direct current is being applied. The newer permanent materials magnetic like iron boron has displace field coil.
At rotating machine, field coil is wrap around iron magnetic middle that guide the magnetic lines field. It is two parts which is rotor and stator. Stators are stationary while the rotors rotate in it. The lines then will be passing in continuous loop that is called magnetic circuit, from stator to rotor the back again. The path will be characterized by the poles or the locations in equal angles circling the rotor.
Almost configuration uses one coil in on pole, though some simpler or older arrangement uses single fuel wire with pole each end. Wire used at wind field coil should have low resistance to reduce amount of strength that it consumes. It is important because the excess heats at the wires are common cause in failure. The increasing in copper cost, the field coil is often being combined with aluminum.
Going through the articles and then trying in cleaning the confusion about difference between the fields and rotor. The article had text that indicates that fields of motor were always on stator and the armature always the rotor. For generators, the coil that mounted on rotor and supply through the slip rings.
Permanent motor magnet uses the magnet in supplying flux field. The magnet motor has excellent torque starting that has the capability in good regulation of speed. The disadvantage of this is that somehow are limited in number of loads that they could drive. Those motors could be found in lowly horsepower mechanisms.
