Self accelerating reed switch magnet spinner.

@MileHigh: thanks again for your help.

On Thursday I will buy this 12V DC motor:

http://www.conrad.at/ce/de/product/244475/Igarashi-Igarashi-Motor-mit-5teiligem-Anker-12-VDC-Leerlaufdrehzahl-244475?ref=searchDetail (the specifications should be clear even in German)

May be also this one:
http://www.conrad.at/ce/de/product/244478/Motraxx-Motor-mit-5teiligem-Anker-12-VDC-Leerlaufdrehzahl-244478/?ref=detview1&rt=detview1&rb=2

I have a variable DC power supply 1 V - 30 V (3 A max). The above first motor can be driven from 6 V to 24 V (0.35 A), the second one from 10 V to 14 V (0.25 A).

I guess the experiment with various "pick up coils under test" and a rotor (diametrically magnetised big ring magnet or cylinder magnet) driven by the above DC motor should be done like this:

- define a fixed distance of the "pick up coil under test" (its face) from the rotor (e.g. 30 mm)

- define a certain rpm under which the rotor should spin (e.g. 3000 rpm)

- put the  "pick up coil under test" at the defined distance from the rotor and make the rotor turn with the defined rpm by changing input Voltage (with the variable power supply)

- once the defined rpm of the rotor stabilises, measure the output of  the "pick up coil under test" (over a matched shunt, true RMS)

- the output of the  "pick up coil under test" and the Wattage (Volt and Ampere -> Watt) necessary to drive the rotor with the defined rpm gives an indication of the "quality of the pick up coil" (its capability to generate electricity)

- all  "pick up coils under test" which are to be compared have to be driven at the defined distance from the rotor and with the defined rpm of the rotor (and the same rotor)

Everybody interested is invited to refine this "measurement protocol".


@synchro1: The well being of the world depends only in a very very small way on you and on me. So stay calm, there is time. Be good.

Specially for synchro1, some facts about Reed switches. Switching frequencies above 20 Hz will produce unexpected results. Switch time is around 50 ms.

Driving a magnet spinner with a reed switch will be problematic above 1200 rpm (20 Hz).

It is not forbidden to try higher frequency switching with a Reed switch, but the results will be unpredictable. But there could be a conspiracy about 400 Hz switching with a Reed switch (24000 rpm), watch out.

@Conradelektro,


I plan to switch your experimental comments on the Tesla Spiral over to the Tesla's "COIL FOR ELECTROMAGNETS". thread soon, where they belong. Surely you can appreciate why it makes more sense to include your current comments on this specific area into a background content of related charts and findings.


I restored the thread to the roster, and copied Milehigh's latest comment to it. Please direct the remainder of your comments about the Tesla Coil for electromagnets to the newly resurrected thread.


Thank you,


Synchro

@Milehigh,

Here's what you have to say:

"In the first Igor clip you linked to, there is no BEMF looping back to the source.  The BEMF discharges though the diode".

Here's what Igor has to say in his Youtube comment:

"Just got another setup with the same idea to capture (utilize) some energy from bemf spikes (which gonna be lost anyway); it's running longer".


Here's a second quote from you:

"In the second Igor clip you can see the current consumption increase on the power supply when he showed increased output when he inserts the rod into the coil".

Here again you apparently see something there that's totally imaginary on your part, that's completely misleading and contrary to the facts represented in the video. Igor clearly states there's increased "Output current", this is over any apparent rise in input. Igor's reporting and demonstrating a gain here!

"I did some tests with bedini setup and found out that similar to TROS it might work as a breaker for magnacoaster circuit, yet, current increased by using a core with a magnet on it with opposite to rotors' magnets pole, in the way the magnacoaster used for increasing voltage AND current"


Your chronic and persistent twisting of the facts is truly revolting. You just flat out pretend Igor's results are fake. You never even conducted so much as one experiment. You're the fake! You remind me of the old Lorilard tobacco institute that maintained cigarette smoke contained vitamins.

Folks, take a look at this quote from Conradelektro from earlier in the thread:

"I am interested in this type of coil because I could feel this "rattle" in my fingers (which means "some strong force"), but the rotor did not slow down (the tub magnet has to be at a certain distance from the spinning magnet). That is interestingly strange. Maybe this "vibrating magnetic field" induces more current into the bifilar winding than one would expect. We will see, thank you for disclosing your observations I will try to replicate".

Ask yourselves what Conradelektro did wrong to get the failed results he posted? Practically everything I told him not to! Now he's dropped the "Synchro Coil" project cold!

Quote from Conradelektro:

"I will move on to pancake coils".

Just what went on? Does this failure of Conradelektro's have any connection to Deepcut's completely devestated web archive? Deepcut was in the midst of exactly the same experiment with me when everything of his suddenly and mysteriously grew deeply censored.

It looks to me as though Conradelektro just "Chickened out". Furthermore, we can anticipate any forthcoming results of his to be contaminated by the same brand of cowardice.
