By definition, the direction of the current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial charging magnetic field. The two opposing magnetic fields being forced together is what the motor has to overcome and why the amp draw of the motor goes up when the generator coils are under load.
In other words, as a magnet approaches a coil that is connected to a load forming a completed circuit, a magnetic field will be formed in the coil that opposes the field of the approaching magnet. At top dead center the field in the coil flips polarity, attracting the magnet that is trying to move away.
Read Tesla patent 512,340. In it he describes a method for winding a coil so that the capacitance of the coil is increased to the point that, when the rotor with a proper number of magnets on it is turned at the proper speed (fast enough) the formation of that opposing field does not occur soon enough to repel the approaching magnet. If it is formed at exactly the right time there is NO reaction at all (and the generator coil produces the MOST power). If it is formed s bit later, just as the rotor magnet passes top dead center, it pushes the magnet away in the direction it is moving. Less power is produced by the coil in this case.
Per Tesla:
"I have found that in every coil there exists a certain relation between its self-induction and capacity that permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance, or, in other words, as though it possessed no self-induction. This is due to the mutual relations existing between the special character of the current and the self-induction and capacity of the coil, the latter quantity being just capable of neutralizing the self-induction for that frequency."
Because there is no opposing field under load, there is no increased amp draw of the motor when the coils are under load. My motor pulls 12 amps at 24 volts whether there is a load on the coils or NOT.
The trick was figuring out how many wires at what length to wind a coil that would match the number of magnets I had on the rotor turned by the specific motor running on 24 volts at a specific rpm. Anything under 2800 rpm and I do not get the effect. Too much rpm and I get speed up under load or lens assist, and power output goes down. It took over a year to figure out all the variables and put together the perfect coil for this machine. But ANY coil will work as long as you can figure out how fast the rotor has to turn for THAT particular coil.
Tesla also says you can increase the capacitance of the coil by using a capacitor along with it and get the same result, but I have never tried that. I do not remember if he said in series or parallel, but I imagine it was in series.
