pedal power

@
Lakes: thank you for the web addresses for pedal bikes, I noticed no one was using a large flywheel to smooth out the loading. mmmmmm                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   @Magluvin: I do have air inside the coil! I know it is possible to mix fine metal shavings with epoxy and fill the coils, but this creats heavy cogging, due to magnetic attraction,,but increases the output of the coil. I have aDC motor that I turned with a drill motor, but was really surprised at how much  HEAT that thing put out when hooked to a load, even a small wattage light bulb. I was wondering how it would hold up to long term use , with no cooling air flowing over it?

Cogging can be smoothed out with asymmetric core centers. Like when one mag is being pulled toward the core, the other is trying to get away from its core. Each coil can have its own rectifier and cap, then you can series parallel as needed. Also like you said epoxy, the mix can be weak to compromise between cog and power out. JB Weld already is magnetic. The 2 part epoxy only the 'metal' part is magnetic. But their 2 part putty sticks, both the outer part and the inner part are magnetic.  You can tape off the coil and just mold it in. 

What size DC motor did you try with the drill?  Cooling fan motors can take some heat. And some of the pancake motors, they are nice and compact and can take or give some good power.

This is a fun one.

This is good too.

Magluvin? I guess that means you take a liking for magnets? cool handle!! My DC motor was from an old mikita cordless drill that I wore out along time ago, actually the chuck was stripped so I tore it apart and saved the motor!  it was 12Volt, I hooked up a 12V light bulb and spun it up with my new cordless drill. the motor got so hot I had to let go pretty quickly, or I would have burned my hand!

Lakes: Those last two that you showed do have flywheels, but they are on the small side and pretty inneffective, as there is no weight concentrated out on the rim. The flywheel I have in mind is  a min. of 5 ft. dia. and weighs at least500lbs.
