List of homopolar generator patents
From Wikipedia, the free encyclopedia
A homopolar generator is an electrical generator in which the magnetic field has the same polarity at every point, so that the armature passes through the magnetic field lines of force continually in the same direction. The device is electrically symmetrical, and generates continuous current. Some of these devices also have "homopolar magnets", which have pole pieces arranged around a common centre. The United States Patent Office uses the clasification class 310 (Electrical generator or motor structure) and subclass 178 (Dynamoelectric; Rotary; D.C.; Homopolar) for these devices. Many of the homopolar patents were obtained prior to 1975. Below is a list of homopolar generator patents.
