Hi y'all!!
It's me again...  ;)

I just done my experiment...  :)
The result is exactly same as Groundloop...  ;D

I have the same question here...

How to kill the battery!!  :D



Thanks!!
Have a good day...  ;)

@ lon92

If you don't have access to a lawyer or a politician to drain the life out of your battery as Cap-Z-ro mentioned (can't stop chuckling over that one)  ;D please refer to Reply #146 where David mentions  "If you flip the switch and yours starts up, you know that you do NOT have a dead battery in the #3 position, so go find a DEAD one."

There are several posts where David talks about the dead battery and it seems critical that it needs to be completely dead so I think that if the dead battery is able to sustain any kind of voltage it's not dead enough.

The battery that I'm using has been dead for several years and doesn't hold a charge for long but even though the motor started up after several minutes after the switch was turned on Battery 1 & 2 were depleting and not recharging in my experiments so I'm still waiting for the proper motor to arrive. 

I'm afraid that if this does work it requires key components as David mentioned in Reply #45 where he says "Going back to the very first experiment I did with my original motor, two batteries and my original dead battery and start over"

Regards,
Paul

Thanks Goat for your reply...  :D


I just retry the experiment  with a dead battery...
Just like you, the battery died about 3 years ago...  ;D

At earlier test, the motor not rotate even an inch...

After about 5 hours, the motor start to spin slowly... Its alive!!  :D

The motor run at the same speed for a day until the batt. 1 and batt. 2 exhausted... 

Odd...  :-[

@All,

I can't get hold of the CIM motor so I tried something different. First I "tuned" my
motor impedance with a coil in series with the motor. Then I noticed that I got "big"
sparks when I connected or disconnected the motor, so I added a diode to harvest
the back emf voltage created between the motor and the coil. Now the motor slowed
down a lot and did not use so much power from the batteries. The 12 Volt 25 Watt
light bulb kept the "dead" battery at a low voltage and the light output was very bright.
(I estimate 1/2 the full light output from the bulb.) Then I just let the circuit run for
3 hours. The motor did go up and down in RPM but did not stop or start. Now comes the
"funny" part, both my charged batteries was drained a lot before I started the run. Battery
1 was just 11,7 Volt and Battery 2 was 10,6 Volt. During the run I saw that the voltage
over both batteries go down but ALSO sometimes UP. It was NOT a linear drain as expected.
I aborted the test after 3 hours because my two input batteries got slightly warm to the
touch. Next test will be with a home made coil. I will try to make a coil that I can tune
on the fly when the circuit is running.  Small steps........

what is the effect of this circuit?
The motor is running an 24 volts. the back EMF from this Motor
harge an battery with (only) 12 volts.
Can i find any additional power on the output that comes not from
losts from the 24 volt input-battery (2 time 12volts
(

@pese,

The effect of this circuit is that both input batteries gets discharged after a while.
I'm trying to change that.

@All,

OK, my tunable coil is done. I tested this setup but my input batteries is depleted and
needs a charging. Will be back later........

Hi All
Just a quick update...

I received the CIM motor today and hooked it using 2 12V 7.5 Ah batteries on #1 & #2 and several different "Dead" batteries on #3. The motor started up on everyone of the dead batteries so I'm still looking for the perfect dead battery out there to get this working with this particular motor  :P  Figured I'd start with the 12V 7.5 Ah batteries and work up to 18 Ah batteries if needed, the present 12V 7.5 Ah batteries are getting the motor running so I'm gonna try to find a better dead battery which will be cheaper than buying 2 new 18 Ah ones :)  If not I'll upgrade if needed  ;D

Here are the specs on the (FR801-001) motor that I got if that helps anyone in comparison to the one that David used:

Banebots FIRST CIM 12V 5280 RPM 345 oz-in Brushed DC Motor
• 5280 no load rpm at 12V
• 12V nominal voltage
• Stall torque: 343oz-in

The Banebots FIRST CIM 12V 5280 RPM 345 oz-in Brushed DC Motor is a CIM motor identical to the one supplied by FIRST (FR801-001). This motor is LEGAL for FIRST competition use. Also available are 56mm gearboxes for these motors to make great robot propulsion systems

Dimensions:
• Diameter: 6.2cm
• Length (without shaft): 11.2cm
• Shaft Length: 3.3cm
• Shaft Diameter: 8mm

Specifications:
• Voltage range: 12V or less
• Nominal Voltage: 12V
• Stall Torque: 343oz-in
• Stall Current: 115A
• Kt: 2.98oz-in/A
• Kv: 442.5 rpm/V
• Efficiency: 65%

Banebots Number: M4-R0062-12

@ Groundloop .... Thanks for all the help this far and good luck on your latest  ;D ;D

Regards,
Paul

@ Goat:    I'm gonna try to find a better dead battery which will be cheaper than buying 2 new 18 Ah ones   If not I'll upgrade if needed.



Getting a DEAD battery is NOT difficult, just leave a 12V Car Headlight Bulb on it until it runs down.  Or leave a 12V Motor Home 25 watt or 50 watt Screw In Light Bulb on it until it runs down.  You will have a DEAD battery.  It is really easy.

Thank you.

@FatBird,

I highly disagree. What you are describing is a drained battery.
A dead battery is defined as a battery that you can't recharge again.

@All,

I'm giving up testing on this circuit.
All I have seen in this circuit is draining of batteries.
I hope others get some better results than I have.

 hi all  :D, i strongly agree with groundloop about the 'dead' battery thing - ive been fully charging, draining, shorting for days and days on end my yet to be bat3, ive lost count of how many times and it still conducts first off - this is a mission in itself! lol
and in the same thoughts as groundloop - i may put this to rest before too long also

@david, i guess youre a busy man but we need more info in the sense of, your bat3 residual voltage from idle for say an hour, the current and voltage you draw across the motor when its doing its magic and the actual motor wattage, is the wire in your circuit all the same and what rating? - these i believe are some missing important parameters in our replication setups - please please please if you can. I realise youve revealed loads of info already but the aforementioned would be very helpful im sure - thanks


catchya all soon,
eel

Hi All

My project hasn't moved yet so I can't comment other than there are still lot's of variables in the equation :P

I'm not using the exact same motor and batteries.
My motor doesn't have a gearbox as David's had.
I still need to find the right dead battery if needed.
I still need a couple more specifics on the dead battery, maybe the ones I used were too dead  ???

@ Dbowling

Looking over the history of your posts these 2 strike a cord  :o  Was your "partner in crime who helped me build this thing in the first place" using the exact same components as yours?  If so, what changed in your second circuit when you changed the motor?  Was it only the brushes of the motor or anything else?

I spoke with my partner in crime who helped me build this thing in the first place. He has been running tests on his own with his own machine so that we could compare notes. He isn't having the same problems I have so we are meeting tomorrow afternoon and I will post after I talk to him. I don't know how much he has been running his or what tests he has done.

I just hooked up my whole system using the old, less powerful motor I used on the first day, and now it's working right again. I hooked up the motor I was using this weekend and it doesn't work right. SO apparently something went on inside the motor that screwed me up. Possibly wearing out the brushes with all that sparking. I don't know. But once again I am able to charge a battery and the voltage in my main batteries either stays the same or increases, and the motor runs the whole time. I will be charging up four batteries now and then discharging them through the Kill-A-Watt to see how many hours of power they put out. And doing it again and again. Kilowat hours of electricity is the "standard" my electrical engineer friend wanted to see.

Sorry for all the questions  ::)

Regards,
Paul
