. Why such technology has not found before?
Induction motor already has the capability to become grid tie induction generator when it goes 7% to 10% above it synchronous RPM. Slower turning device can achieve it by mechanical mean (speed up gearbox). This creates a sentiment of an unnecessary effort; the reinvention of the wheel.
. I'm wondering why you wouldn't first try to get this published by someone like Nature or Science or other peer review journal so it can be taken seriously by the mainstream crowd.?
Eventually yes. After we gather enough information and of course our resource allows us to do so. We are still in 24/7 to get it out of the door. (Thanks Allen for the question) Or If someone can help? Please! We certainly are very very welcome.
. What is the NEW basic theory this based on?
For us this is new discovery. It is: An induction motor can be DC 'amplifier' when it is fed with a pulse like DC.
If you are a religious person you can look at my forward page.
. What is the efficiency rate of the system?
To be very honest with you. We don't know the exact number. The rates we provide are only based on educated guess base on the laws of physic. The input power is all converted into electricity minus heat and friction (also heat). Based on study of the motor when it is running at its full load, the heat and friction overhead is form 4% to 6% of its rated power. To be safe we can say the overhead is about 8% to 12% of its rated power. The reason we double that amount because when an induction motor becomes a generator its pole to pole voltage are elevated up to 50% of the power source. Its also safe for us to say that the generator only be positively power generating when its act more then 10% of its capacity.
. (At times we encounter this question) You are using the grid to generate power to the grid then what percentage we are using compare to the output?
Honestly we do no know how to answer this question beside speaking of the nature of the induction motor then refer to the efficiency rate above.
. What is a bare bone system ?
The so called bare bone system is the core system. It allows induction motor to act as induction generator as long as it turns. As the rule of thumb; the faster you turn from 0 to 10% of the synchronous RPM the more you generate electricity. The result RPM (after loaded) dictates the output of generator. There is no mechanism to turn ON/OFF; and imperatively requires an on-duty operator.
Beside the cost of the motor, The bare bone, basic unit will cost an amount . . . . next to nothing. However one adds features into the device we can not say!
. Do the utility company have any idea If I want to install one?
As of Texas, the utility companies post regulations on the "induction machine", Such regulations are the very minimum requirement, one need to have device including manually cut off device, over/under voltage relay and over/under frequency relay such as equipment contribute the protection to both parties, you and the company. You indeed like to install them yourself anyway.
. What motor should I use as generator?
Please remember, that when an induction motor functions as an grid tie motor, (inside the motor) the voltage may add a 50% to the voltage it receives from the grid. In most cases a simple 110/220V won't work as the '220V' generator. However it's OK. to configure as 220V 'motor' and only apply the 110V grid.
The selections of the choice for single phase 220V generator are among those 240V delta /460 Y three phase 1800RPM. Internally this type of motor has 6 coils, and arranged as 3 groups; each is having one coil opposite in both location and polarity to the others. A connection these three groups in serial fashion will make it to tolerate up to 480V safe for the 220V motor. In this case one will also have the choice to make it either 3600 or 1200 synchronous RPM motor too.
For three phase environment, it is a different ball game; (at this moment;) it works as three single phase motors put inside one housing. For US 460V three phase electric system; each is 277V from phase to ground; operate those would require a 277V + 50% tolerant on each group - A motor that allows a 460V Y connection can do the job. The break down method also allow to use three smaller, generators one per phase.
. Motor? Those are around the house, in the garage ?
The good answer is a big NO! NO! NO! A generator runs much different then a motor; first it has higher terminal to terminal voltage, secondly it has a lot of torque to turn it. and thirdly it may produce a lot of amps. While the motor only getting hot when (a lot of) torque drags against it. - In most cases; those motors have electrical bottle neck (the past abuse causes somewhere at copper wire a bottle neck) even it's "looked new" but it's unfit to run as generator.
Because the 'generator' operates at a low RPM and endures a higher voltage environment its built-in fan is ineffective. Unless one have an add-in measure (fan or liquid), it will not prolong. As the same as the measure applying to the low speed motor; generator needs additional prevention to manage the "over heat". it could be either by electro-mechanic or electronic sensor device.
As of the nature of the renewable energy device; slow speed; and this contribute to more than 90% the cause of the failure, in general, one should not think of using a gearbox unless the device turn too slow as of the waterwheel. As long as it continuously turns, and with the help of a controller one can get the most out of it; an electronic 'gearbox' is more reliable, needing not mechanical lubrication and not subject to wear and tear.
. How to determine the motor size ?
Unless you have a deep pocket to use a dynamo meter and they are pricey for the slow speed device (if you can find one?); Other than that you need to try on error, using smaller one first. Please note that most wind turbine has 'rated power' Please don't take that as guidance; our experience; many of them don't even come close to that amount.
. Why it is for education and experimental purpose only and not to be connected to the national grid?It is just that! We don't want to get into trouble with any of the law suits. When dealing with high voltage, someone's life may be in danger. It should be done by qualified personnel. And only the local utility companies will have such authority, not us.
. Can I buy your product ?Our main product is our consulting. Our society are too familiar with "product liability" when it is tangible. As of today we can only afford to make a transaction if we are free from any liability of the use, its purpose or any others resulted consequence. Of course you can ask us to share you our kits for can build one yourselves. 'Experimental' and/or developer modules are also available.
. What technical matter I should aware of ?One of the most important matter is the recursive phenomena; there is not a technical name for it yet; Not-Yet. The induction motor converts mechanical force to electricity as if it is an "amplifier" by elevating the received voltage. This amplified current is then fed back to the generator to be amplified, the process is repeated and repeated . . . until the power of the grid neutralizes to keep it at a stable voltage level. Therefore others external circumstances such as its location; how far from the grid and the wire size does play a role to help to maintain it at a 125%-140% the voltage elevation. We believe this are already exhibits along with the old style induction generator; however it becomes noticeable now. One more note: Not all the chips (in the same family) are equal.
. Are there other unknowns . . . ?
This presents a pioneer application based on a 'new discovery';. There is no book nor any other published information, nor any study specific to this YET! No matter how hard we try, we indeed can not cover all the aspects. We find and learn something new everyday; thing we have not been aware of . . . They are waiting for the great minds, and adventurers of they are yet to come.
