pulse motor Working video and info

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.

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.
