ABSTRACT:
A columnar solid body rotor for DC dynamo electric machines in which a cylindrical dust core, obtained by solidifying a finely powdered magnetic material with an insulating material such as a synthetic resin or the like is mounted on the rotor shaft and a closely wound winding is disposed on the outer periphery of the dust core. The volume-conversion permeability of the rotor is selected several times higher than the space permeability, thereby to increase the effective flux of the rotor.
