Pulse motor speed run + HV oddity noted
A scrappy quick build…results of which to be taken forward for the FanGen project and others. The rotor is made from the bearing and now bladeless innards of a 12V PC fan. It was noted that the ball bearing assembly gave a little noisy but very smooth spin when the 6 magnets were positioned on the outside. So, this is simply a speed run in the first part of the vid. The second part shows HV generation through field effects of the coil. it’s not the standard effect often seen and doesn’t use a coil shorting method. Only when the rotor speeds up does HV appear, by way of partially lighting the neon bulb (90V AC needed for neon to glow). At a constant speed there is no glow, as the rotor decelerates there isn’t either….only when the rotor is speeding up. That effect may be useful within future builds and experiments. Power is a bridge rectified and capacitor smoothed 12V wall adapter. Output is just above 10V. Amp usage seems to be around 5mA, when tested across a 2.2ohm 1W resistor.
