In a YouTube video, user ubozkurt1 gives the rotor on his Perendev replica a push by hand to get close to what appears to be a resonant speed which then appears to be maintained by the magnetic interactions alone. Visual and audio analysis conclude "constant speed".

On Dec. 26, 2008, YouTube user ubozkurt1 posted a video of what appears to be a test jig showing just two magnets in a rotor to demonstrate the concept presented in the famous Perendev all-magnet motor.
In this video, ubozkurt1 gives the rotor a push by hand to kick-start the rotor. It takes several tries to get close to what appears to be a resonant point in a speed which then appears to be maintained at a constant speed by the magnetic interactions alone. He then stops the rotation by hand and starts it again with the same effect.
Off to the side, you can see a rotor that more closely resembles the Perendev design seen ubiquitously on the web, and featured here at PESWiki (we own perendev.com, which forwards to our page).
Lightrider, who is expert at analyzing such video footage, analyzed both the video and audio components of this video this past week and concluded that there is indeed a stable speed achieved almost immediately and maintained until manually stopped.
We don't know of any replications of this effect, but if there is not any trickery involved in this video, it would constitute a validation of the Perendev all-magnet motor.
Stefan Hartmann, of OverUnity.com, said that the replicator apparently is Turkish. "Somebody of my forum speaking Turkish language emailed him; and he said, that it worked, but that he is only an amateur tinkering with this stuff." He's not posted any more videos and has not communicated further that we know of.
Here is ubozkurt1's video:

Interesting but I did observe one thing that kinda got me wondering...
In the builders attempt to 'start' the device it 'kick-over' (started actually running) on the 5th pull.
For God's sake, Sterling, do you not know a SMOT ramp when you see one, yet? How many have you see to date, 1000? Come on, man. It doesn't work as shown, it's not even worth a debate, let alone a story.
Sotty, thought it sloped, it doesn't. It's some other form of electrically powered bullshit.
It's not a SMOT ramp if it keeps running. And apparently this does.
I have to wonder, though - this is over a year old: what has happened to this guy and his work? It would be nice to hear more from him - his specs, his exact geometry, what is on the tips of his neos, etc.
