Alexander-Planas Generator Idea

4/2 - 4/4/2011 Revised 11/11/2011

The Alexander motor (patent 3,913,004) is a very good idea in that the permanent magnet can be used to add flux to the steel cores. This should create a higher voltage to the secondary coil so that more power can be drawn from the secondary coil. Also in the case I am presenting. I would pulse the coil till the magnet gets to the 45 degree mark. Then the power cuts off so that the attraction of the magnet creates another flux change which can be collected by another coil (which I’m calling the horizontal coil) without having any input power. This would be 1 half of the idea…


Here is what the Alexander patent idea looks like. This makes the idea easy to visualize but my idea is to have the rotor be the permanent magnet and the stators are the coils. From this you can see how both mutual inductance and motional electromotive force are present factors on the transformer of the input to output coils.

The next set of images is a 2D electromagnetic model of the motor/generator idea I have come up with. There are 4 electromagnet stators and a permanent magnet rotor. The vertical electromagnets are the input power coils. The horizontal ones pick up excess power generated from the movement of the magnet rotor.














In this graph every number on the x-axis is a shift 15 degrees rotation counter clockwise like the pictures above show. From the pictures number four is where the current cuts off but is shown at 1 amp indicating that by around 46 degrees or so the current should cut off. The input coils are set at 3000 turns. With this many and the area of the coil being 28.5 square inches that would mean a wire gauge of 32 AWG would need to be used. Although this is unrealistic for 10 amps to be drawn through the coil, less current could be used and it would still work.

The idea then in this case is that the coil can be pulsed where power is transferred from the input coil to the output coil and the movement of the magnet would create a flux change in the secondary which would create a higher power output. Then power could also be collected without any input power by the attraction of the magnet to the steel core of the horizontal coil.

The next step is a repeat of the current pulse and this allows the horizontal coil to be purely generating coils. This next set of images shows this process which is the second half of my idea.
















With this motor idea I propose that the pulses of the input coil could drive the magnets movement. In the drawing above it would be the vertical coils shown. The secondary coil which is wrapped around the input coil would be power generated for output loads. The other coils horizontally shown could be used to generate power which could be used to power the input coils. The way this could work is by using horizontal coil flux generated. The idea for the way this works is from the patent 3,673,423 by Planas. Using this patents circuit the second pulse could turn the magnet to the full 180 degrees.



The pulse from the horizontal coil could charge a capacitor between leads labeled 4 above which would drive keep the motor running. The motor then could be run without a battery and only by the recharge of the input capacitor which would be initially charged by a battery or by the induction of voltage to the horizontal coil from the kinetic energy input to the rotor. It is important to note that the Planas circuit is powered by AC source across leads 4. It also states that there is one pulse generated per half cycle of the AC waveform. This means that the capacitor would have to pulse half its energy and then the other half its energy to create the initial pulse then the 90 degree pulse. Since the flux change through the horizontal coil is positive from 0-90 degrees and then negative 0-180 degrees it could work as the power source of the AC wave form. This means that there would be 2 cycles of voltage created for every 1 cycle of rotation created.

The Full idea sketch is shown bellow. As you can see slip rings or some other electronic means would be needed to flip the current going through the input coil so that the next 180 degree pulses would occur.
