BEMF can never become OU due to hysteresis, eddy currents and resistive losses.
This is disputed.

It was also said we could not fly , from educated people in the past.

...and that if we travelled faster than 30 mph, the wind
pressure would suffocate us.

Hi Jesus,

I would like to suggest a modification in the schematics you composed.
Now the TC4429 is fed from the 5V voltage stabilizer.  This means that the 4 MOSFETs receive a maximum of 5V driving pulse as the gate-source control voltage,  and this value is near to the threshold voltage (which is anywhere between 2-4V, see data sheet http://www.fairchildsemi.com/ds/RF/RFP40N10.pdf ). While the MOSFETs are surely open for the 5V, no doubt,  their gate-source ON resistance, rDSonwill surely be higher than what would be achieveable by running the TC4429 from the 12V voltage stabilizer. 
If you see the rDSon value from the data sheet, it is specified as 0.04 Ohm at 10V gate-source voltage input, VGS,  normally such power MOSFETs need at least 8-10V gate source control voltage to obtain the specified ON resistance. 
This modification would make the 5V stabilizer redundant, while the power loss on the 4 parallel MOSFETs will be less, hence switching efficiency can increase.
If you agree with this, than the supply pins of the TC4429 (that are tied to the 5V stabilizer)  would connect to the output of the 12V stabilizer, that is all.

Thank you @gyula !

Will you be so kind as to make the changes you want on the graphic in order for me to understand what you are explaining so technically.
I will gladly make the changes and learn something on the go.
Remember I have no electronics background.

Now just what is your point? People drive motorcycles faster then that, with out a helment in Florida.
