This is something that i have been working on. Havent quite got it figured out yet. some principles. If the motor motorises 1 way- the residual magnetisim is in that direction. Then if i drive the motor in that direction It wont generate un till the charge coil wires are reversed.
On the residual magnetism, this is good for generated EMF but also is the cause of the BEMF in the motor coil as BEMF and Generated EMF is the same thing. As far as transformer action is concerned, the residual magnetism may work against us as the varying field will not vary so much but the transformer action also reduces flux in the motor coils reducing torque, the residual magnetism may be a benefit in this case as it will increase flux in the iron cores partially compensating for the loss of flux.
The generation in the second coil occurs in the opposite direction to the input current in the primary as does the transformer action so these should work togeather for our benefit but I think you a right about the geometry, I will have to be changed.
So the motor action and generator action must be 90 degrees out of phase. If i rotate it the other direction it wont charge at all. Untill maybe the residual magnetisim is reversed. Just therory as of right now untill i can verify it.
I think the charge cycle in the armature has to be wound at 90 degrees to the motor cycle in the armature. Also is the BEMF 180 degrees out of phase. If this is the case to make use of this the part we want to use for the BEMF has to be wound opposite of the initial positive voltage to make it work for us. this will push the rotor ahead. im just throwing some things out there for us to think about.
As I said we will have to change the geometry but I suspect it might not be as much as 90 degrees. It isn't that the BEMF is 180 degrees out of phase, its in the opposite direction and out of phase
Just some things to consider. The trifflar coil off the motor side could have been, with one of the windings to get a lot of BEMF back in to the rotor was switched or pulsed. if it was wound in series to ground from the second motor coil which was i think both north poles. So the generator coils would have to be south poles. then we can go from there as to how we think the gen circuit works. Motor coil and gen coil use 1/4 of the armature. creating a vortex in the center of the armature for some extra energy to come in. Like in Walter Russels coil drawings. Just some of my thoughts. The light at the end of the tunnel is getting closer.
Inductive kickback, transients, transformer actions and BEMF are not the same thing, they are four different things. BEMF and generated current are the same thing and occur as a result of a magnetic field cutting a coil. With the trifilar coil, assuming we have no magnetic fields cutting it, will have a varying transformer type field and so a transformer action will occur. As we will switch off the current rapidly we will also get inductive kickback which is a ramp down of current equal to the energy stored in the capacitance of the coil, that is able to impedance match its load (in other words it can be connected to a higher voltage output than the input as well as higher resistance but it will contain the same energy no mater what the load is), on top of this we get a transient of high voltage which has negligible current.
It is likely that this coil is in series with our motor but will not be effected by the magnetic poles in the motor however it may have an influence on them. As it is effectively wrapped around the same iron case, it may increase flux in the iron increasing torque. As it is likely to be of very low resistance there will be little losses so only giving a benefit in this manor. Our rotor will be disconnected electrically from the trifilar coil when the inductive kickback occurs but the magnetism could increase flux in the motor core causing more torque.
To be honest the vortex field makes my head spin
I suspect we can see the light at the end of the tunnel but I don't know how far it is away, every time I think I have it, I find a new problem to solve.
Was the 160 volt rise the same direction as the positive voltag in put or was it the reverse. Was just wondering if it was the BEMF doing it or how the voltage was built up. Is this with the rotor you rewound or a different one. Also is the rotor all series wound connecting to each commutator section. This is definitly somrething to persue farther. Could be the break were looking for. Thanks.
The transients are in the same direction as the voltage, that is if the voltage is more positive the spike is positive, If the voltage is going negative then the spike is negative. Its not the BEMF, It is the inductive kickback and transient. The rotor is lap wound (standard) but with a break in the wire in one place. Its a partially burned out motor. The key here is the gain in the transient, with my modified rotor I will get exactly this effect but in one direction when running on DC and we collect it in the output coil. Each Time I find something relevant, I post about it but no one seems to understand what the relevance is
To sum up, we have a generator action and transformer action in the same direction at the same time but we need to move the location of the generator coil to maximize the generator action. We have an increase in magnitude of the transients with no increase in input power. We have inductive kickback. We have a loss in flux due to the transformer action but residual magnetism may compensate for this to some extent and if we wind the trifilar coil around the motor this may also compensate for flux loss. In all these actions we have only one iron loss and one friction loss.
Now lets do a thought experiment.
If our motor is 35% efficient, friction and copper losses are 15% and the iron losses being the remaining 50%
We input 100w so that 35w are converted to mechanical power and 35% of 35 watts is the inductive kickback power so now our mechanical power is 47.25w
Our generator will only have copper losses as the iron and friction losses were paid by the motor so lets say it is effectively 95% efficient giving us an output of 44.88w of generated power.
Our transformer action again will only have copper losses so lets assume it is again 95% efficient. But do we consider the 100w input for the transformer action or only the 35w after losses? I will assume worst case so we have 35 + 12.25 inductive kickback x 0.95 so we get another 44.88w, giving a total of 89.76w output of electrical power.
This isn't enough but wait, now we add the Gray circuit using the capacitor to recycle the energy put in the motor. now we have 35 + 12.25 x 89.76% additional power to play with or another 40.28 watts giving us an output of 130w. All this without the trifilar coil.
