VOLTAGE, AMPs & POWER

Many people ask me, how can I produce the electric energy for my "Lowracer hybrid"? That's normally impossible...
The answer may be easier like you tought!!!

What are you using as a controller? Instead of using a converted alternator I've been considering using a permanent magnet motor and a Dc-Dc converter when I'm pedalling with an automatic switch to change over to my LiPo4Fe battery when I'm tired or from a standing start. I figure that way I'd get the best from both forms of energy.

@ronald44181000

A controller doesn't exists! It only comes 6Volts over a diode to the rotor coil. The diode is needed, if I pedal faster, so I can get a higher voltage than 6Volt to the rotor and of course a higher output from the 3phases..... That means also, I MUST PEDAL for driving, a driving without pedaling is not allowed by law!

I just came across this charge controller on ebay that will allow me to run on pedal power and then when it produce more power then the battery can withstand it'll send it directly to the motor. Flexcharge Wind Turbine Charge Controller NC25A-24

For wind, solar, hydro or a hybrid - 24 volt

provuded I only use a 24 volt system. For here in Ontario, Canada thats about the limit our speeds are regulated on electric vehicles to 22 kph. For electric vehicles.

I can't complain about the power of the 4motors, sometimes the tire smokes!

Take a look into my video "LiPO-POWER", there I combine lithium polymer cells with super caps. But in that system I'll work with nominal 37V and a range 32V until 42V.

I work in the industrie, 24V is a good standart Voltage, but the cables example for a hub motor are limited. So I must select a higher Voltage for more Power (P=UxI)

yeah i lived in snow and 3 months of sun before. i liked the cold though but i guess that is irrelevant. have fun and Schéi Chrëschtdeeg dude

[ChrisLuxembourg]

Merci gläichfalls, schéin Chrëschtdeeg an e gudde Rutsch!

I can only pedal 150-180WATTS!!!!!!!!!!! In my new LiPO battery are nearly 6hours of pedaling included, in this time I could be everywhere!

I don't live in Hawaii, I live in Luxembourg and in winter we have only a few hours sunshine. So should I need now an nuclear-powered bike???

If you think a disc with a lot of strong magnetics that's the true, that was my first idea before 3years:

LOWRACER HYBRID / Cobalt-Samarium

[punas1]

would it be a three phase sprocket if you added 2 more rows of sprockets with magnets that would be staggered behind each one all connected parallel to the alternator. May be that would increase the effort from 150-180 watts up to 450-540 watts that would be faster. Also COSTCO in Maui Hawaii is selling a photovoltaic portable unit that will generate 300 watts just from the sun I'm sure that would be cool. Its only 281.00 EUROS right now

[ChrisLuxembourg]

I've created a chainring with 99sprockets, thats my biggest one! The mechanics and the electrical power is nearly unlimited, but I only can pedal 150-180watts!!!

[punas1]

i wanted to ask why you didnt make sprocket larger?
