STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Jimboot]

I reversed the polarity of 1 mag of my 3 mag setup and now it will only spin counter clockwise. Uploading vid now if anyone interested. I have reverted to the reed switch setup as I can't get hold locally of pn100 & 200 transistors.

Hi Penno,

Yes that is a hall vain sensor from Jaycar that I have cut the built in magnet off. This sensor is good because it can be powered with voltages from 4.5-30 volts.

I can post a circuit but it is not much different then the mosfet-hall sensor circuits shown by others.

The large toroid ofcoarse can be wound with more turns of thinner wire to reduce the current and increase the efficiency but my goal was to simply show a working concept motor.

To further increase the efficiency and torque of this concept motor the core must be laminated to reduce drag on the rotor.

Regards,

Ossie

Please correct me if I'm wrong, but this circuit does not appear to be even in use in the demo unit.  Are they intentionally trying to throw everyone off?  Or am I just looking at this wrong?  This circuit is in the second red wire, and appears to be in parallel with the first red wire running to the battery.

(Edit) That trace may run backwards and make connection.  If so, that whole circuit board is in place for 1 diode? Why not just solder a diode?

There can be components on the other side. The path is not ending, where you point, perhaps a leg of transistor is soldered there. You can't say much without looking at the other side.

Anyway, I'm surprised, nice detective job.
