series field in series with the armature
shunt in parallel with the voltage supply
the shut field increases the strength of the magnetic field with
heavy loads
to reverse the motors direction the fields remain the same you swap the armature leads

What is shunt current and a armature current?
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.
Does armature rotates?
Typically the armature windings are in the stator of a generator, which does not rotate. Typically the field windings are on the rotor, which rotates.
What is interpole winding in DC machine?
For a D.C motor it is the field windings which must always be in series with the armature windings.
Why is alternating voltage induced in the rotating armature of a generator?
The windings of the armature are constantly cutting magnetic lines of force of opposite polarities
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
How electrical genrator work?
The stator and the armature are both wound. An excitation current is applied to the field(stator) windings from a DC source like a battery in order to produce a magnetic field. The armature is connected to a turbine or diesel engine via a shaft. As the armature turns, it's windings cut the magnetic flux of the field windings inducing an emf in the armature windings.

How do commutating field windings cope with the effect of armature reaction?
Commutating field windings are connected in series with the armature windings so that the current flowing in the coils is always equal to the armature current. The number of turns in the commutating field windings are also equal to the number of armature turns. This means that the field strength of the commutating windings and the field strength of the armature are always equal. A DC motor is constructed so that these two fields of equal strength oppose one another, they therefore cancel one another out. The main field is now unaffected by armature reaction.
Does armature rotates?
Typically the armature windings are in the stator of a generator, which does not rotate. Typically the field windings are on the rotor, which rotates.
How does a small generator produce current?
It doesn't! It produces voltage. It does this by the relative movement between an armature (winding into which a voltage is induced) and a magnetic field (set up by field windings). Either the armature rotates inside a fixed field (small generators) or the field rotates within a fixed armature (larger generators).Current is only supplied when a load is connected to the generator.
Does the stator and the armature each have the same number of windings?
No.
How do you determine which windings are field on a series DC motor?
Both the supply wires that enter a series motor is the field windings the field is split in two and is connected at the split to the brushes that is connected to the commentator of the armature, so the current pass thru the first half of the field then thru the armature and then thru the other half of the field. With a parallel DC motor the two fields is in series and the two wires is connected to the brushes so is the supply.
What is interpole winding in DC machine?
For a D.C motor it is the field windings which must always be in series with the armature windings.
What are compensating winding?
compensating windings are used to overcome armature reaction
Why is alternating voltage induced in the rotating armature of a generator?
The windings of the armature are constantly cutting magnetic lines of force of opposite polarities
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
