Bendini motor to run itself

[Goat]

Hi All

Not sure if this would work but here goes Just thinking out loud in case I get hit by the bus of life tomorrow 

One thing I noticed a while back was that whenever I first connect the the SSG circuit I got a jump in voltage on the Charging battery before even starting the wheel. 

I replaced the Charging battery with a run capacitor off a motor (40 MFD 370 VAC start cap) and if I just touch the negative terminal of the Primary battery to complete the SSG circuit I get 28 VDC in the cap.

Now if I start the wheel that 28 VDC will climb to several hundred Volts in a matter of seconds but will light the NE2 which is hard on the transistor 

Here's the question I've been wondering:

What if you placed a switching circuit that connected completes the ciruit then disconnected the circuit completely and dumped the 28 VDC charge back to the battery, would it charge the battery or would it drain it because of the energy used to bring the cap to 28 VDC?  It does seem to charge it faster than just connecting the battery to the cap because of the BEMF of the circuit somehow.

If that doesn't work would it be possible to increase the timing of this switching circuit and turn the wheel and discharge the cap fast enough not to hurt the transistor while back popping even more voltage to the battery and getting rid of the second battery from the circuit?

I tried this awhile back using a 555 circuit but it was tied to the main battery and blew the circuit because of the high voltage and slow timing and I haven't tried it since because I figured it probably be easier to do it of the wheel using a commutator and brushes, just haven't gone back to it yet.

Not delving into Bendini much myself more on the thought of power cycling though (something i do think about ) Can i suggest a cross linked Compas relay to switch between batteries so one charges as the other discharges?!? it takes a bit of fiddlings but the theory behind it is if you wind a small coil and have a "floating" magnet it will align itself with the magnetic field... as your battery power drops so does your electro-magnets field then once it realigns to its natural state have a dual connection (both batteries) and the one with the best charge will have the strongest pull on the magnet and it will align with those connections... Cross the output connections with input connections and the batteries should rotate through as they discharge...

Just a thought and because this is no mainstream idea (they just use electronic switches instead, another possibility) But still an idea

Hi All

Well I decided to try something that I never tried before and although it took some messing around and tweaking on the POT but my Bedini wheel now seems to be running better than ever WITHOUT the charge battery in the circuit  Just a cap as in my last drawing but with a motor in parallel to the cap so that it acts as the switch to back pop the battery through the motor acting as a fast switch   

Although my battery voltage went down from trying several different circuit configurations it's now been running for 30 minutes at better speeds than before and NOT stressing the transistor while maintaining the present battery voltage and running the little motor across the capacitor 

Guess I might have just found a solution to the fast switching solution 

I'll keep you all posted

I can see why you haven't posted for a while. You have nothing useful to say.

You are a prat, Pinestone. What Bourne says has been confirmed many times.

I wonder if it is because the driving coil is involved in a hot electricity application
whereas the pickup coil is about cold electricity.

If the bendini motor can put out more power then it takes to run, then why cant you connect it to itself
and have it run off it's own power and still charge something else?

I wonder if anyone has applied to a Bedini an automated two pole two throw switch (is this right?) to swap the batteries over,
on the fly, every ten minutes.
