You can check 27+ pages how to reduce armature reaction in dc generator answer in PDF format. Armature reaction affects the flux density in such a way that the flux density over one-half of the pole increases and decreases over the other half of the pole. Thus by increasing length of air gap the armature reaction effect is reduced. Thus by increasing length of air gap the armature reaction effect is reduced.

To neutralize the cross-magnetizing effect of armature reaction in a DC machine a compensating winding is used. 28Armature reaction has few effects on the dc generator which are written below.

In a DC machine the main field is produced by field coils.
20The cross-magnetizing effect of armature reaction in large dc machines can be neutralized by using auxiliary winding called Compensating Winding. The compensating windings consist of a series of coils embedded in slots of the pole faces. The armature teeth and air gap at pole tips offer reluctance to armature flux. The effect of armature reaction can be neutralized by placing compensating winding in series with the armature. The armature reaction flux will induce conductor voltage that causes the commutation problem. 17The effect of armature reaction can be reduced by 1 Increasing the numbers of field turns to produce additional main flux 2 To increase the reluctance of the cross magnetizing field path.
