Hey Ren,
How did the testing go with motor....just wondering.

hey mate,

Testing went good. I have now placed another 5 sets of magnets around the wheel for a total of ten. The output from the secondaries went from 20 v to 30v. I was a bit skeptical of this reading so I hooked it up to an analogue gauge. It read 5 volts with 5 magnets and now reads 10 volts with 10 magnets. I dont know which one is correct, but I have to go with the 10 volt reading on the analogue, so as not to get ahead of myself.

Ordered some halls today and transistor, looking forward to seeing how they perform.

Amps went up on the input side however to around 1.6 amps. Im guessing since I have doubled duty cycle per revolution that its using more current. Is there a simple circuit I can buy/make that will allow me to make adjustments to voltage and amp draw from the battery?

Output is enough to turn hobby motors, and will light up a 12 v 5 watt bulb, not to full brightness though.
I have got heaps more ideas for it yet so stay tuned.

Ren,
To reduce the current your motor is using, you will need to place a resistor inline with one of your coils. I suggest doing it right after the micro switch. A standard light dimming switch is probably the easiest and most robust for the price, a cheap one will do. Using the dimmer, you can vary the current going through your coils.

I brought a 1k varible resistor yesterday, would that do? I am going to go and make a vid now. Post it shortly.

Ren,
If you have resistors available to you, putting on inline with the dimmer switch is a plus. You just need to figure out how much current you want running to the motor and match that with a resistor of correct rating. This will be trial and error.  Here is a website  to figure out what your resistor is rated at. Just change the color bands on the resistor on the web site to match the one you are using.

Yeah the 1 k should be fine, just start at full resistance and work backward. Also make sure the resistor is rated above the power you are using. 12 * 1.6 = 19.2 watts, as long as it is 20 to 25 watts it should be fine.

ah ok, thats why it didnt work. rated at .5w lol. So when I get a proper one I should install similar to the way you showed me to install amp meter reading, i.e current flows through? Just after the switch huh.

heres a couple more vids of tests.

yea... always inline with the current. I've burnt alot of components trying figure out how to use them. :P Just trying to save you the trouble of that.

I like the videos....Good work!
Once your figure out the transistor circuit you will be amazed at the difference. make sure to be ready for 1000's of rpms. Just be careful. Good luck

I am hanging out for this circuit. Hopefully I can get it sorted soon. The microswitch is overheating and losing speed after about 10 min running.

nice. Looks like you have got some good equipment there. Have you considered adding more coils to that setup? Oh and by the way any idea how many turns on your coil? Or weight of wire?

I believe the coil is either 1/4 or 1/2 pound of 24 gauge and 26 gauge wound in bifilar. Sorry, I wound these coils years ago....but i would guess 1/2 pound each. The coil is 2 inch by 1 inch approximately.

My next coils to test are 24 on 24 gauge bifilar wound. We will see how that works.
