 Fuelless power

I sell all my electronics-, motor-, generator-, coils-, magnets, tools-, and relay stuff

Good day,

(I hope I can post this here, if not please advise me or set my post to where it belongs to.)

here I offer a 12,5kw electro motor/generator built with the construction plan from Creative Labs (Fuellesspower.com), called SP500 Model 2.
I lost my interest for this hobby entirely and therefore sell everything: all accessories for the motor, including tools, parts, many high-tech measurement instruments, relays, enamled and non-enamled copper wire, ring terminals, capacitors and more.
I would prefer to sell it all as one set (apart from the crimp terminals, and copper wire) and first sell its parts when nobody wants the set. Though I really want to get rid of it, so don't hestitate to write me!

Shortly, what it is:
It is a heavy 1m x 55cm x 70cm motor made from HDPE, 30kg copper coils, 39pcs N52 2"x0.5" Neodym magnets, with commutator, capacitors and accessory. You can use it as a motor or as a generator, depending on how you set it up. The set includes everything you need for both variants.
It also includes high-tech measurement instruments for a nice surveillance of what's going on inside.
Further, the set includes all tools such as hole saws, forstner bits etc. as well as spare HDPE material for extending the motor.

Here the parts list:
- 3 HDPE stators, each for 8 coils, 50cm (20") high, 45cm (17") wide, 4cm (1.57") thick
- 6 HDPE rotors, each for 8 magnets, roughly 40cm (15") diameter, 1,8cm (0.7") thick
- 2 HDPE housing walls for the left and right, each 2cm (0.787") thick
- 20 coils with an inner diameter of 4cm (1.575"), an outer of about 9cm (3.5") and 4cm height (1.575"). They are made of about 30kg (66lbs) 17awg high temperature resistant enameled copper wire, and are hard glued with epoxy.
- 39 (and one broken) N52 Neodym magnets of 2" x 0.5" size (50,8mm x 12,7mm).
- 1 keyed shaft made of C1018 Cold Drawn Steel with a length of 36" (~95cm) and a diameter of 1" (2,54cm).
- the same keyed shaft cutted into 2 pieces
- one more keyed shaft with the same properties but only 0.5" (1,27cm) diameter
- steel bearings SF205 for all three shafts. They aren't fixed to 90° angle and the shaft could be positioned else.
- 25 capacitors CBB65A 450VAC
- 1 commutator for the motor made from aluminium, epoxy, and HDPE.
- 10 coal brush pairs for the commutator.
- a housing for the motorbrushes.
- 1 ultra fast diode RHRP860 600V
- male and female power plugs
- several relays: SSR-40A-H, SSR-10 10A, SSR-40DA, SSR-40AA-H
- heatsinks, not enough for all relays
- 1 rectifier bridge diode KBPC5010 1000V 50A
- DSO138 Oscilloscope
- digital LCD powermeter, simple and cheap with 6 functions, 5KW 20A, and panel mount
- multifunction power meter, 3 phases, alarm function, RS485 port, and panel mount
- intelligent power meter, with 26 functions, 3 phases, alarm function, RS485 port, and panel mount
- 4 split core current transformer with a ratio of 100 and stereo plugs for the power meters
- 4 female stereo plugs
- digital tachometer with alarm function, RS485 port, and panel mount.
- 2 proximity magnet switches 12V
- RS485 USB adapter
- 3 mini 2 position switches 125VAC 6A
- useful connection cables
- 8x 8mm (0.314") 1m (39") long screw thread rods
- 6x 6mm (0.314") 25cm (10") long screw thread rods
- More than enough screw, nuts, washers, and medium split washers; 12mm, 8mm, 6mm, 4mm (0.47", 0.314", 0.23", 0.15")
- 20x 6mm fixing screws for the keyed shafts, long
- 20x 6mm fixing screws for the keyed shafts, short
- spare HDPE sheets of 3 different sizes: 20mm (0.78"), 12mm (0.47"), and 3mm (0.113") thickness.
- 1L (1 quart) epoxy
- all hole saws for extending the motor; 140mm (5.5"), 2x 95mm (3.74") one deep-cut one normal, 90mm (3.54"), 60mm (2.36"), and a set of tungesten hole saw from 12mm (0.5") to up 55mm (2") of 16 pieces.
- forstner bits mostly fitting the hole saw sizes, as well as a high speed steel set in a wooden box with inch sizes ranging from 0.5" to 2.125" of 16 pieces.
- high-precision Automatic Voltage Regulator for 230V output
- 5000 separated M6 ring crimp terminals
- 5kg (11lbs) 19awg enameled copper wire
- roughly 5kg (11lbs) 1,8mm diameter (approx. 13awg) blank copper wire


All about the motor:
The motor is designed as having for each coil two magnets, one right, one left. You may have noticed that 3 stators each for 8 coils and only 20 coils won't work out. Thus one stator functions like a half-sized half-phase unit, either as generator or motor. Also the magnets don't suffice for 6 rotors neither. Therefore the third stator goes between the two rotors of the two other stators. Nevertheless there are 7 + 1 broken spare magnets for extending the motor, for one because the other rotors are already made. Or you use the magnets for other projects.
The carbon brush commutator is made from HDPE, aluminum, and epoxy, like creative labs describes it. Also capacitors, the necessary diode, its heatsink, and if it was necessary rectifier diode are there. The capacitors are readily connected in a small HDPE housing, for security reasons. It has an easy connection through the M6 crimp terminals, just like the stators. I obviously also made some fitting connection cables.
The coils and motor are adapted to European 230VAC standard by giving the coils a one awg thinner wire and more turns. If you require 120VAC you could simply connect a transformer at the output, or even better an Automatic Voltage Regulator (AVR) for 120V. The one I offer here is for 230V only though.
In order to be able to change the arrangement of the coils and their connection, they are currently only screwed in, and not glued in like the construction plan suggests. Once you have decide for a definite connection scheme and order, you could glue them in with the epoxy included in the set.
To acompain the high-precision AVR, I bought some good quality, state of the art survailance and measurement instruments. I am especially proud of the tachometer, since it is one you just can't normally buy in low quantity or as a private person. Unfortunately I got the wrong proximity switches, for 12V and not like required for 230V. Yes 230V. That's another drawdown, you will have to use a transformer if you live in the US. Fortunately all other measuring instrument are designed for 100-230V power supply. All of them (apart from the cheap small one) feature alarm functions with one or more alarm outputs as well as RS485 port for surveillance via computer or even internet. Since this motor is rated at 12,5kw I equpied the power meter with some nice split core current transformers for measuring these high currents.
Further, all measurement instruments are panel mount style with the same front size. I designed the housing of the motor in a way that they have space and that they will be mounted in a 45 degree angle. Also other wiring and transformer-similar stuff has space. This is also the reason why it is so big. If you put it all as close as possible together it would probably be just 50cm (~20") long. And therefore you could easily double the number of stators and power.
The stators are 2x the 20mm sheet, and the rotors are 1x 12mm + 2x 3mm sheets. Since the magnets are just a bit thicker than the rotor disk, the two 3mm sheets have notches and serve as lids.
You have all material and tools needed (apart from machines) to extend the motor either in number of rotors, size, or whatever other ideas you may have. Nonetheless, there are two things you will likely need the spare HDPE for. One thing is that there isn't a cover yet and since the rest of the 3mm sheet doesn't suffice, you would have to use the 12mm sheet. The second thing, which is the only major drawdown here, is that you may want to renew the holes of the rotor disks. I didn't have a high-precision drill press and the professional I paid apparently neither, and thus the holes aren't drilled in a perfect 90° angle. Therefore the rotors create some vibration and some wobbling. It still works on high RPM though. You could either use the circles, that are left over from making the holes for the magnets and coils, by enlarging the current rotor hole and screwing the circles onto them, or you make the rotors anew. However you decide, there is enough 12mm sheet for the cover and the rotors because there are more then 2m^2 (10.7feet^2) left. The 2m^2 is one big sheet, which I would cut for the shipment into your desired format. But there are also some more, smaller 12mm sheets left. From the 20mm sheet there are only small pieces left, like the circles from making the holes.
I also built a mechanic translation with a belt so that you could connect another spinning force, like a windmill to it. I got the mechanism from a washing machine.
Creative labs claims this motor produces an effect that is called overunity. I couldn't achieve it. May it be that I didn't have the patience to finetune the motor, or that I did something wrong or whatever. I don't know. Anyways, this is only the secondary reason I sell it.
I think that at least the parts serve somebody for his/her motor/generator project, and in the best case it someone searches for it as a hole.

Organizational matter:
Preferably I sell it all as one big set, as one shipment to one person. Therefore, I will wait one or two months until I sell parts outside of the set. You can write me nevertheless and reserve the item, just in case nobody wants the set. If you have a question though, I think the best would be you post it here in the thread. Also, subscribe to the thread, if you are interested in something of it. I will keep you updated here.
Nonetheless there are also things I sell outside of the set. If you buy the set however, you will get them as well, as per your wish.
Shipment:
The shipment will probably be parted into several parcels. Unfortunately it is very expansive from where I live and if you want a tracking code, it even costs twice as much because it's called premium here. I guess in the worst case it might be 1000$, depending on where you live. If you live in Europe though, it will probably be just around 400€.
Single parts like 20 magnets, one measurement instrument or whatever can easily be shipped for 50-100€ (60-120$)

What I sell outside of the set:
- The crimp terminals. Yes there are almost 5000 crimp terminals for M6 screws. You can solder a wire to them or use the crimp function. Both works well. You can have whatever quantity you like. I'll send it cheap as a letter, if you don't want all 5000 at once, obviously. I really want to get rid of them, so you will get them for a good price.
- The enameled
- and the blank copper wire are also both outside of the set available, since they don't have any function in the motor.

May it be what somebody is searching for.
Cheers!

There is a section at the forum for selling.
Look for it, then copy and paste this over there.

Thanks. First after a google search I found it, it's kinda hidden.
