My Window Motor - Charges Like SSG

[HeairBear]

Here is a pic of my BediniSG window motor! What? It's in a window! It's an old pic I dug up. It was unfinished at the time. And believe it or not, it was stolen! I haven't finished the rebuild yet. Maybe someday...

Wow! Someone stole your wheel? How sad.

LOL! Not just the wheel, it was a finished BediniSG coil and all. I just happened to buy a set of those mag wheels so I could make a new one. I really hate winding coils though, so, finishing the replica has stalled. WillbyInebriated and I spent many hours researching Bedini motors and he has a few builds of his own. If I really need to know or experiment, I just go to him or ask guys like you who have done the work already. That way I can keep my lazy ass in front of this netbook and water my garden. That reminds me... I better water my garden...

Ok guys I have some good advice! I have to share this with you!

I used to think that Reed switching and Hall sensors were too difficult to use on the Bedini Window motor. Well, I tried a Reed switch and I must say, I will NEVER go back to the basic trigger coil ever again. I thought the timing would be hard to figure out. Well there isn't anything to figure out. You just slap a reed switch and some magnets on the end of the shaft, and you have a running a motor. Move the reed switch one way, the motor slows down, move it the other way, it speeds up.

Now.. Here is the part that I didn't understand before. The Reed switch produces high voltage radiant spikes at ALL rpms. Current draw is strangely reduced by 40-50%. I am not completely sure why this is  , even though the torque appears to be just as good or better.

The reed switch triggering turns the Bedini-Cole window motor into the perfect DO IT ALL machine. You get torque, variable speed, and HIGH voltage radiant charging. Now, we have something more practical than the SSG, since you are still getting tremendous "back EMF" radiant spikes, but you can also do useful work, all while drawing 50-150 ma.

I used the basic window motor half circuit. But instead of using the trigger coil, I just stuck a reed switch in it's place. One end of the Reed goes to the Base of transistor, the other end goes to a 2.2K resistor, then to the + battery.

The "on time" of the power coil is dependent on the width of your little trigger magnets. With my tiny magnets, I now have REDUCED on time, meaning I cannot run the motor FOWARDS or BACKWARDS. It will ONLY run one direction now. If you want a clockwise rotation, move the reed switch one way. If you want a counterclockwise, move it the other way. Now you have a motor that won't start up backwards. It can't.


INPUT VS OUTPUT:

9V @ 50 ma - 100 volts output

9V @ 150 ma - 225 volts ouput
