## Losses In Electrical Machines

Losses in conventional electrical machines are too high and arc due to magnetic drag, eddy currents and hysterisis, and consequent high operating temperatures.

It was with the above problems in mind that I was prompted to find a way of over-

coming the aforementioned losses, the result of which evolved in a machine of beyond-unity capabilities.

As the 'Adams Motor' is a pulsed direct-current device, there is no change in polarity of the external source; therefore there are no eddy current losses, and hysterisis loss in the motor is minuscule; with new materials becoming available for stators, the small loss incurred would disappear. It matters little, however, as the machine efficiency is such that such a minuscule loss is negligible.

With reference to magnetic drag, this too is virtually nonexistent, due to the unique design of the machine. A rotor pole, upon leaving the attraction area of the stator, is at a precise geometrical pointâ€”and is suddenly repulsed, thus overcoming any possibility of magnetic drag taking place.

Having outlined the above, I will now explain something regarding magncLic drag that won't be found in classical teachings or texts: a rotor, once in motion, is mutually attracted to any stator in its path. On leaving the stator area, however, the stator causes a drag-back effectâ€”classical teachings do tell you that much. What classical teaching does not tell you is that the energy in the initial attraction equals exactly that which causes the drag upon leaving the stator area. This is where classical teaching is found wanting. The original attraction and secondary attraction exactly cancel one another out. Magnetic drag, therefore, docs not exist in the straight motor version of the 'Adams Motor' invention. The machine is pulsed before the trailing edge of the rotor magnet can be affected. Should the timing be a little out, the effect would be minuscule.

Having discussed the aforementioned factors, there is little to explain regarding the very low operating temperature of the 'Adams Motor', as a result of which it does not require the use of a cooling fan with lis own efficiency loss to counter.

It has been noted in New Energy News under the title "High Current Brushes", on making use of silver and platinum for commutator and points: this news is nol news to me as, during my research in 1976,1 used these materials myself for the above purpose. It appears, however, from this article submitted to New Energy News that the method for their use, being researched, has good prospects. I, for one, look forward to learning of the progress in this direction.

In 1976 I learnt of the high losses of my commutator system and first used silver for the star disc and platinum for the points with considerable success, and having since used photo and magnetic switching with remarkable success. Having, of course, kept my research and experimentation to myself over the past two decades for reasons associated in the main with the establishment, and latterly with international patent law, I was forced to withhold all my machine's secrets up until my recent decision to publish certain aspects of my work earlier this year.
