A Suggested Homopolar Motor

G.R.Dixon, 7/18/2006

Fig. 1 depicts a variation of a dielectric disc/ceramic magnet subassembly introduced in a previous article. In the present case, and for reasons to be explained shortly, the peripheral copper ring on the dielectric disc extends slightly beyond the periphery of the ceramic magnet.

Fig. 2 repeats the top view of the dielectric disc, with embedded copper bars (or wires). In this case the ceramic magnet would be completely hidden behind the dielectric disc.

Fig. 3 depicts the suggested stationary motor. It is a variation on the toy vehicle discussed in the previous article. Note in the present case that the copper rims (around the dielectric discs) on either side are in contact. (Hence there is no need for a conducting belt.) This of course means that the discs on either side counter-rotate. Since the apparatus is not now rolling along a surface, this counter-rotation is of no consequence. Again, the batteries rotate with the discs. The shafts output mechanical power and could be combined into a single load drive-shaft using sprockets.
