Adding more coils increases the speed. The motor is running too fast for my liking in the video. I can increase the coil numbers( more coils) for more capture of back emf by pulsing them at different times. I just want to maximize the single coil capture before I do that. This is trial and error for me at this point. How much resistance do i need for "motor excitation". And how to keep the motor running slow enough to maximize the coils magnetic fields for capturing the collapsing magnetic field.

Well I just uploaded a second vid to youtube. It shows the motor running on 2 volts at 5 milliamp, charging a cap to 40+ volts. Just playing with the motor now to show different variables. Having a variable power source is well worth the money, I can control the voltage and amperage this way.

Hi borg,
reply #41 is the setup, however the pickup coil and the driving coil are wound as one coil ( two wires). I have not shown the resistance (on the drawing) on the pickup coil which is 2.6 k ohms. hope this helps. And remember that this is only possible because of the massive magnets. The magnets you see will tear your fingers off....no kidding. If you plan to work with magnets this size, please wear welding glove at the very least.

amazing. I Love it Jase. Your right, those magnets are massive. Must have been an effort to align and fix them to the rotor.

So i am thinking I might try this setup as my switch just cant handle long periods of use. You say you had a 1.5k resistor with a light dimmer also on the circuit. This is positioned before the diode on the drive coil circuit? What model transistor did you use and what diode, or should I just go get a bunch and start testing?

Also mate, if I was to hook this up I would be best to build a circuit for every coil I have rather than run four coils through the one transistor yeah?

Use the 1.5 and the light dimmer on on the pickup coil to "allow" the transistor to let the current from your battery to flow to your driving coils. This will be between your base and emitter of the transistor. Basically, the pickup or trigger coil ( one in the same) will allow the current to flow to your driving coils. Once enough voltage is between the base and the emitter then current is allowed to run to your driving coils to turn the motor. Hope this helps.....damn beer, don't know why I drink it.  :P

I use a tip3055 transistor, the diodes shouldn't matter to much at this point.

To answer the last question about a circuit per coil, I actually find it better to use two separate coils for a motor you want to run at high speed. But since speed isn't the issue, bifilar coils works well. This is all just a learning process to help you understand how energy flows. Once that is understood, then the real fun begins, along with the headaches.  ;)
