Abstract: Armature reaction in a dynamo is reduced by constructing the main pole structure and/or the commutating pole structure with a plurality of iron lamina arranged parallel to the axis of rotation of the dynamo. The iron lamina are separated from each other by nonmagnetic or magnetically weak material of a predetermined thickness designed to cause a predetermined minimum but high reluctance to be offered to flux generated in the main or commutating pole structure as a result of armature current. The core of each pole may be split into a first and second core half at the root and in the direction of the axis of rotation. Each core half has a larger portion which extends to the adjacent core half of the neighboring pole, thereby forming a yoke. A smaller portion of each core half extends into the air gap between poles and, together with the corresponding portion of the core half of the neighboring pole which is similarly extended into the same air gap, forms a commutating pole. Each iron lamina may be constructed of a plurality of sublaminas which are glued together.
