Hmm, not a bad idea that... Maybe a big v belt around the wheel with the tire removed would have less wear?
Six of one a half dozen of another. I think for your design I'd have to create something for the bike tire to roll on though, I'm sure the pully is too small and too close to the alternator fan. -Curt Date: Wed, 02 Jan 2008 15:42:15 -0500 From: Mitch Haley <[EMAIL PROTECTED]> Subject: Re: [MBZ] OT: Cheap generator To: Mercedes Discussion List <mercedes@okiebenz.com> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=us-ascii Curt Raymond wrote: > I'd bet the Cub Cadet generator I mentioned is happiest around 1200rpm The Delco S/G you mention doesn't seem to do much below 1000 engine RPM, and the crankshaft pulley is lots bigger than the S/G pulley. I bet it hits 10,000 rpm at redline (where it can easily peg the 30A meter if the regulator sticks full on). I'd rather use an alternator myself. I like the idea of using a rheostat on the field of an old 35A Bosch alternator or similar. It might be easiest to use a standard rear wheel, and put a drive roller on the alternator rubbing the tire. There is some friction loss and tire wear if you do that, but it makes the drivetrain simple, with a very high step-up gear ratio. I saw one that used a 24V wheelchair motor for a generator, I think it was in Homepower 5-10 years ago. Nice recumbent frame design so you could watch TV while powering the TV, without craning your neck. More efficient than a car alternator, but lots more $$$ than a salvage alternator.
