GM used for stationary exercise bike electricty generator

clinford2001:
I could use help knowing how to retrofit a GM in place of the rear wheel of my road bike turned exercise electricity generator.   What do I need to do to make it happen?  Is a GM motor the best solution for a bike generator???  Any help or direction would be appreciated for attaching it and making it work effectively...

Um you plan on pedaling for watts.  For watt,  I mean for what?

The best direction I could head you in is reverse, but yes it is possible, and if the solar winds destroy all our mobile phone batteries and the power is down for a week it may be worth getting some exercise on that bike you're making.

Before we embark on an epic exercise bike can I ask you a few questions.


How much power do you want to gain by doing this?.  

What practical application do you want this for?.

If your were told this isn't worth wasting time or money on for your needs would you still continue?


Here is the easy way to do what you want.


Remove brake pads

Lift wheel off the ground.

Switch controller on.

Apply regen brake

Pedal to all hell against regen.

Keep pedaling more.

Look at the appox 32 watts of energy you made for your 10 mins effort.

Hire a slave to do the rest. :D

Edit:

Hey it's not such a bad idea.

You could make a gym with 20 of these exercise bikes and charge people to use them.  All the time they are giving you free power.  If you can get all 20 bikes running, 200 watts per hour x 20 bikes is 4000watts.  :o

Edit Edit:

Serve the gym members high caffeine content energy drinks at cost and watch the watt meter rise

Leslie:
I just saw the poll up there.

The answer is fluid.  You could make both work at this low level of power generation.

Depends on the resistance you can put on them for charging.

I'll pick the cheaper lighter unit. 500 watt.

Watch the Youtube video labeled "Brushless Hub motor as 3 phase generator"

You'll find it under:  http://www.youtube.com/watch?v=OD1gSx92DuM&NR=1


What do you think???

As a wind power generator, Wind power is awesome power.  He could get well over a 1000 of watts with a wind prop and much more with a bigger motor.

40 watt isnt that much, although it looks impressive there will be much loss trying to store it.  A big capacitor in there would help just a little bit.

People must consume food to make watts, this is a bad conversion percentage.

The 6 diode rectifier has been discussed here to some detail.

You could do this with a magic controller too, and vary the amount of resistance via software.  :o

Things are going to be different when you connect the motor to a battery. & with how many volts?  EG a little bulb resistance vs .012 ohms battery. The resistance to the wheel is going to be much more.

Id like to see that experiment done on a decent battery.
