(under subclass 177) Subject matter relating to homopolar dynamoelectric machines.
(1) Note. A homopolar dynamoelectric machine is one in which the moving armature conductor is not in the form of a coil, but is rather in the form of one half of a single turn. Generally, this is achieved by utilizing a disk or a cylinder as the coil with pairs of brushes to conduct the current from and to the conductor at spaced points.
