Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

[MoRo]

This gave me the idea of, what if we take an off the shelf brushless DC PM motor which are controlled by 3 hall effect sensors which tell the switches (mosfets or transistors) to turn on and off at the appropriate time ... I'm quite sure in these control circuits they do nothing with the flyback right?... so all we do is collect the flyback and with it power a second motor tied to the same shaft and there you go, a motor that once under load the assist motor will become stronger which should help maintain shaft torque.

This is a very good way to go in testing, Luc.

My thoughts were these:
* the in-line assist motor can be of a slightly larger diameter and have more copper winding (there by providing even greater torque).
* the in-line assist motor staters should be twist adjustable for timing purposes.
* if done right, the in-line assist motor could have its own kickback for a third in-line motor.

I found this video to be a good starting point for anyone wanting to make their own brush-less DC PM motor.

Dear verpies,

could you please do the calculations on my below scope shot.

The input is exactly 2.00 Volts DC
The CSR is 1% 0.1 Ohm
The Capacitor is 9.92uf (measured)
The Load resistor is 1,001 Ohm (measured)

Many thanks

Luc

BTW I rearranged everything to look like what itsu provided so to keep it simple.

Dear verpies,

here is another one in case it looks better then the above.

The input is exactly 2.00 Volts DC
The CSR is 1% 0.1 Ohm
The Capacitor is 17.2uf (measured)
The Load resistor is 511 Ohm (measured)

Many thanks

Luc

Im guessing the question mark after ch2 and ch3 results are because the wave form continues outside of the screen,where as ch1 has no question mark after the resultant number ,as it is the only wave form that is within the screen of the scope. I am not sure how your scope calculates wave form value's,but if i have any of my wave forms continue out side the screen parameters,the calculated results are not correct.

Anyway,now it's time to go catch up on some of your video's
