What is one method of overcoming armature reaction in a generator?

One method of overcoming armature reaction in a generator involves inserting interpoles between the main poles. Armature reaction occurs when the magnetic field generated by the armature winding distorts the main magnetic field of the generator, resulting in reduced efficiency and voltage regulation issues. By introducing interpoles, which are smaller poles located between the main poles, the magnetic field is better aligned. Interpoles are energized by the armature current and provide a counteracting magnetic field that helps to neutralize the effects of the armature reaction. This leads to improved voltage stability and performance under load conditions.

The design of interpoles essentially compensates for the distortion created by the armature, allowing for more consistent output and better overall generator operation.
