what is the voltage constant for this dynamo , meaning how many revolutions does it take to produce one volt (V/rpm) ?

It's been awhile since I bought mine , and since sold the bike, but I remember it's the faster you pedal, the brighter the light type

This is a wonderful light and I am so pleased with it, but I cannot answer the voltage question. Good luck with your move!

Hi Brian! If my calculations are correct... I am calculating about 1/10 HP. This was derived from the following: The manufacturer states on their website that the output of the motor at 50 RPM is 8.5 lb-ft of torque. The equation for rotational torque-horsepower relationship is HP= torque (in lb-ft) times Speed (in RPM) all divided by 5252. HP=(torque x rpm)/5252= .081 HP. I am pretty much certain this is correct. If not, please all chime in and let me know! Thanks!

That is exactly how it works. As the number of cells increase so does the voltage, so does the RPM of the motor.

Sergey---The Proxxon transformer sold in the USA is 110v input, and 12v output to match the several 12 volt tools available from Prox as well as others. The rheostat/rpm control is the yellow knob, the 12v outlets are in a row across the front, the on-off rocker switch on the right front, and holes for small rotary bits on top. I do not know what is being sold in Europe or Asia.... I use mine everyday for long periods, and like it very much. Please note that this transformer and its tools are meant for light-to-medium work, as would be done in a hobby setting for model ships and trains, gourd carving, etc. I hope this helps you...

It says 19vdc (Volts DC) at 2.1 amps. Thanks for asking, because mine was very warm so I moved the power supply to a place where I could get more air to cool off. ;)

I have not used mine with motor running as of yet,I have it in a Rv and used breathing machine ( c-pap) and also had a 20" box fan running @ same time,when first turned on it said it had 12.68 volts,ran both all nite (7 hrs) and when I looked before shuting off it said 12.06 volts so it didn't draw to much.....I have a 200hp O/B and it only has a 35amp alt so they don't put out much amperage,,,,,,,

2800 rpm at the first setting. This thing has tons of power/torque. It's loud. It devours mild steel in a hail of sparks.

11~24VAC/VDC(Non-polarity) - More information and spec sheets at: http://www.seco-larm.com/E960LRb.htm

I cant say except that 12 VDC doesn't mater about polarity. 12 VAC is only 8.5 volts effective or / root mean square

230V 60HZ 1PH. Draws approx 5.3 amps at 3000RPM 230 Volts. Have my cover on and running it at 1280 RPM using 147 watts. That's .64 amps at 230V.

Scott. I used this unit for the RPM feature thus far on a 12v system. I have not used it on a 6v system. So I can't give you a positive answer. Sorry

Since I forgot what the voltage was on my pump, I hooked it up to a variable transformer and it ran on a variety of voltages, including 6v and 12v. Of course, it ran faster at 12 volts...

I'm not sure what you mean by voltage sorry :( but the highest setting on this wand is 410 ! It gets pretty hot.

The rpm is multiplied or devided in the gear ratio. 1/134 would be the rpm devided by 134. This would give you the resulting rpm. For example 3000 rpm motor would spin at approx 22 rpm with this gear ratio. The torque is multiplied at this rpm also though. You sacrifice total rpm for a significant increase in available torque.

I don't know the voltage, but I would never recommend this blender to anyone, ever. Good luck!
