Permanent Magnet Motor Used as a Pedal Power Bicycle Generator Dynamo

from http://pedalpowergenerator.com Pedal Power experiment conducted on the Leeson M1120046 DC permanent Magnet Motor to find out how fast a person needs to pedal to get 12 to 15 Votls DC output needed to charge lead acid deep cycle batteries or powerpack. Experiment performed by Brad at pedalpowergenerator.com This DIY video shows you how to create a DC Voltage output curve of the Leeson Model M1120046 permanent magnet DC motor used as a bicycle generator. Data is collected on a test fixture with a 1 horse power variable speed drive motor that simulates a person pedaling a bicycle at different speeds. The speed is measured by a tachometer and DC volt meter and then put into Microsoft excel to create a generator voltage output curve vs. pedal speed Miles per hour M.P.H.

Why did you abandon this motor for the one that you're currently (no pun intended) using? The motor that your new plans use doesn't look like it could handle 300 watts on the wires coming out of it.

@PatinOmaha The new motor being used today has much more current carrying capability. It has a peak rating of 30 Amps vs. 14 AMps

For the price of one of your bike generators I could have three maybe four solars panels or a really nice racing or mountain bike. 667 dollars shipping not included for the cheapest bike generator on your site get real man.

Bike stand $90, Adapter Plate $70, powder coated sheet metal enclosure with silk screen labeling $90, Adjustable length V-belt $50, customized air cooled generator with pulley $110, included volt meter $10, current monitoring shunt resistor $5, shipping costs $50, 3 hours labor to assemble, test, box, & ship $100, USA gov. takes 15% self employment tax ... not easy.  That's why give you free plans to make your own for cheap.

This is the most educational video I have found on the theory of using PM motors as generators. Brad does an excellent job of explaining the relationship between rotational speed and voltage/current output.

nice video

Whoa, easy with the laser, you blinded me, lol : )

@JavaRatusso I'm not sure on your bike which gear will get you comfortably to 14-16MPH, but on my 21 Speed I have to put it at 19th gear to get there comfortably. This generator is just like pushing against wind when you ride. If you ride slow with a PM generator hooked up to your bike, then you feel almost no resistance, but if you pedal fast, then suddenly its super hard to pedal!

I would like to know when trying to achieve the specified 14-16 mph, up to what gear on this bike would be mostly likely used? Is it a 10 or 15 speed 26 inch Bike? I would think that given the "progressive step up" to a higher gear, the required speed could be reached easily. Great video man! One suggestion though. Use short sleeves if you are going to reach over the moving belt, because that motor was cranking fast enough to pull your arm into the pulleys. Be safe, and thanks again!

You would have to pedal pretty damn fast!!.....:-0
