AC Permenent Magnet Motor

Hi .99,

thanks for looking and posting your thoughts.

Good chances you're right. I will test further and report the findings.

Hi .99 and all,

I would have to agree with .99 that this is an electro-mechanical resonance phenomenon as I have now retested but using a Ferrite core coil and got the same oscillation peak at 9.63Hz using the 3/4" magnet I used in the video demo and then changed the magnet for a 1" round ceramic of the same thickness and the peek frequency dropped by about 2Hz.

I will take the video down since I do not wish to mislead anyone.

Thanks for your input .99 and others.

@gotoluc,

Quite by accident I came across this thread and your YT video. I have been working on a square wave driven air coil / spinning magnet experiment and I see you have already developed a motor that produces some work!

Thought you might be interested in seeing my first crude attempt using rather large coils.

Keep going!

Thanks Dave for taking the time to look at my stuff and posting.

Your video also looks good ... who knows where this will lead us

Thanks for sharing
