The basic concept of the design of a new type of motor is introduced by Dr. Harold Aspden in these three figures reproduced from the author's book. Here is the explanation: Fig. 1 illustrates a horseshoe magnet attracting a bar of soft iron (meaning that the iron would not make a permanent magnet). As anyone who has played with magnets knows, the iron bar will be attracted to the horseshoe magnet. If, as shown in Fig. 1, there is a winding on the bar with current flowing as depicted, then the bar electromagnet will be more strongly attracted to the horseshoe magnet.
Alternatively, as shown in Fig. 2, if the current through the coil on the bar is reversed, the magnetic polarities are reversed and the bar is repelled from the permanent magnet. Fig. 3 shows that one could apply alternating current and with some proper sliding bearings could make a reciprocating motor. The power provided to the motion of the reciprocating bar stems from the electrical energy provided to the coil wound around the bar.
There is energy stored in the air gap between the permanent magnet and the bar electromagnet. That energy from the air gap is used to create a back EMF in half of the cycle. The key is to do something so that one uses the energy of pulling the magnets together, and also the energy stored in the air gap without that energy going to create a back EMF. Aspden shows how that can be done by winding a coil around the entire room in which the experiment is running: "...that winding around the room is all embracing and hardly any flux escapes as a linking flux through that winding. There is negligible back EMF induced as it [the winding] accepts the current which breaks the pull between the magnet and the soft iron. Therefore, one has the situation where power can be generated from the magnetic reluctance action as the poles come together but we input no inductive power to weaken that attraction and so allow the poles to separate to reset them for the next action cycle. This is the recipe for 'over-unity' operation." Fig. 4 (taken from figure 9 of Aspden's book) illustrates how unconventional a motor appears when this outside winding is place around the entire motor assembly. Working with a grant from the U.K government, Dr. Aspden has designed a rotary version of his concept and the motor works! The entire motor is quite unconventional in its design features as is well explained Part I of Aspden's report. Part II of this short book provides further discussion of the ASPDEN Motor (Asymmetric Shaded-Pole Dynamo-Electric Negentropy Motor). Aspden probably had fun dreaming up that acronym.
Part III of this book is the real technical meat of Aspden's work. Here he explains the technical details of the storage of magnetic energy and how one can design a motor to tap back this energy from the aether. If superconductive windings are used, then the heat lost through the current-resistance effect (the I2R loss) is minimized. Under such designs with sufficiently high magnetic fields, it is theoretically possible to get five times as much energy out as input to a device, according to Aspden.
Included in this book is the patent cover page and the claims of Harold Aspden's U.S. Patent 4,975,608, issued December 4, 1990, and titled: "Switched Reluctance Motor With Full Accommutation". This patent, with further patent-pending improvements, may well be the long-sought method to produce an over-unity motor. If you are one of the many persons working with electromagnetic motors, this book should be obtained and studied.
The book is available for $25 (if check drawn on U.S. bank) payable to Harold Aspden, from Sabberton Publications, P.O. Box 35, Southampton SO16 7RB, England.
