Webinar 2 – September 2, 2015
Questions that are answered in webinar 2:
1. What changes/improvements/recommendations do you anticipate will be necessary to convert over to a commercial version of the QEG as opposed to a prototype?
2. Can you explain more about mounting the 1HP motor onto the aluminum angle? I.e., it is not clear to me how you can utilize only 1 bolt so that it is adjustable. It does not seem that it would be very strong or stable as such.
3. You said if you put the motor and QEG on the same shaft that you could scale it up and put, for instance, (2) QEGs on the same shaft. Would the 1HP motor then still be adequate? I would think that you would have to ramp that up as well? Also please comment briefly on the variac in the same regard.
4. Theoretically, looking forward to connecting to my home grid, I would run the output of the QEG into an inverter, which conditions the power output to a useable form and then I would assume that I would need a disconnect and then just run it into my panel via a 2-pole 30-amp breaker or something similar. Is this correct? Is the output 110 or 220? Can you or will you be making recommendations for such a power inverter and procedure?
So for my setup now (I am in the early stages) I would need or want to end up with:
a. A feed for the 1HP drive motor – home run from my panel? 110 or 220 best? Something like 10/3 plus ground?
b. A feed back to my panel for later on – from the QEG. 10/3 plus ground?
5. I have a 3.2kw solar system with net metering already installed at my home. How (again) do you suggest we deal with this if and when we reach the point that we want to interface this QEG with our home grid? I.e., suddenly, the power company will detect that we are generating much more power than we have before. Any suggestions/strategies?
6. Would we be better off to just put the rotor in a vice and insert the shaft that way?
7. Re: off the shelf shaft with keyway all the way through. Don’t they make just a solid shaft without the keyway at all? Because we don’t need the keyway, right?
8. For fine tuning the .075” gap between the rotor and the stator, what about cutting 4 small slots on one side plate(s) so that you could insert a feeler gauge, and then use a material for the side plates that is see-through?
9. So re: capacitors – are you saying that, once we get this tuned, and we know exactly the size of the cap that we need, that we will only need (1) of the exact value that we determined from our tuning?
10. How the gap and tolerances between stator and rotor affects the output power?
For instance, the nominal gap is .013″, what happen is the gap is reduced to .005″.
What happen if gap (radial) is not same in one “ear” to the next?
How about if there is some misalignment in axial direction?
11. What is the advantage of having rotor with multiple “ears” such as 4, 6 or 8, instead of 2 in the QEG?
The same question for the stator if has more than 4, such as 6, 8, etc?
Would be able to increase power density?
12. Are there “high” volume production of switched reluctance motor/generator that can be purchased and modified with goal to reduce the cost?
13. What is the weight of the proposed 10 KW QEG unit?
14. In addition to previous questions, would you indicate approximate power equation?
For instant, power=(dia of stator)X(Numberof poles)X(Number of windings of Primary)/(Number of windings of secondary)X…, etc.
15. I’m interested in 1kw unit, or even 0.5kw, what are requirements?
I believe many more people can afford to buy/build one and so, it will make popular very quickly.
16. Question I asked about weight in my 1st email was answered by Torelco when I contacted with M. Peterson.
Matt also informed his plans offer complete kit which I prefer and I’ll order as soon as becomes available. I assume you’re ok with his plans and you’re providing support…?
Weight of 160 lbs is very heavy and dangerous to work in the home garage or basement (my case). It requires lifting equipment for handling during the assembly.
17. Would it possible to break into two or three cores to be assembled in tandem?
How the electric parts become in that case?
18. If I go the direct drive route, will this impact the exciter coil installation?
Webinar 3 – September 9, 2015
Additional discussion: I have hooked up meters between the core and ground and made measurements of resistance ( showing infinite ) and voltage ( showing 0 ) when the motor is off ( that’s to be expected ) – also when the motor is running but the system is NOT yet in 1st resonance – and this was a surprise – also when the system was brought into resonance and the output lights were on, we still had no light on the florescent tube between the core and ground. NOTE all these test were made as a baseline with the antenna and exciter coil NOT connected.
I just went online to find a 1HP motor and boy what a jungle.
(1) So how specific does the motor have to be?
DC versus AC
1HP 1.5HP 2HP ?
2500 RPM there is a lot out there with 1750RPM
7/8” or 5/8” shaft
(2) Im looking at a motor TREADMILL DC MOTOR 180 VDC 1.25 HP 4700 RPM CW
http://www.ebay.com.au/itm/TREADMILL-DC-MOTOR-180-VDC-1-25-HP-4700-RPM-CW-SPARE-PART-/251751913134?
and not sure if this will do the trick.
