Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Hi Sam
just incase you missed my previous post Skate board wheels are 53mm and come with race low friction bearings  ideal for glueing magnets on.

Thanks for the tip Peter. I think I've got some old skateboard wheels somwhere and I'll check them out. I'm glad to hear you got your motor running on 4.5v. It looks like you are on your way.

Cheers

It will probably affect how you have to set your hall sensor timing.

Hi DB

I have been experimenting with the hall sensor timing, and it does not appear to have a great effect on the waveforms. Although I have still not received the Crouzet relay and am using a 3132 bipolar hall sensor with another ssr.

Originally I had the three sensor magnets on the flywheel positioned at 15 degrees forward of the south rotor magnets which caused the hall trigger to correspond with each spike on the waveform. However this did not change the waveform. Moving the flywheel magnets to 20 degrees forward of South, caused a slight curvature of the top flat part of the waveform taken at D2 - bringing it closer to Mike's.

After looking at your last waveforms, I can see what is causing the flattening of one excursion of your waveform.

Hi Darren

Many thanks for your diagnosis. I will have a close look at the diodes.

Cheers

Sam,

What circuit are you working with?  (I'm losing track of what everyone is doing!)
Are you using Mike's original modification of the Bedini, or some other circuit?
