ABSTRACT:
A homopolar rotary dynamoelectrical machine used as motor or generator has a dense magnetic flux area and sparse magnetic flux area in the air gap between the confonting pole of the main field yoke, the sparse area being in a by-pass yoke which is positioned closely adjacent the side face of the confronting pole. Thus magnetic flux affecting the conductive member becomes diluted in the area of the by-pass yoke, and in the area where the by-pass yoke is not positioned, the magnetic flux affecting the conductive member is kept as it was. Accordingly, generation due to the difference in the amount of magnetic flux is possible.
