More magnetic motors... These may have application for electric assist bicycles.

Video Description:

Harry Paul Sprain magnet motor

This is the first OVERUNITY magnet motor released to the public ! It produces more mechanical power than needed electrical input power for the electromagnet. It is the video from Mr. Paul Harry Sprain. I had signed NDA for it and now he has released it to the world !

It is simular to the Takahaski design and Mr. Sprain has got a patent for it.

The electromagnet at the end of the spiral stator switches for 28 Milliseconds the field to zero flux density, so the rotor can escape the stator fields.

For the rest of the rotation circle the rotor is purely accelerated into the track. All magnets are in attraction mode, stator and rotor magnets
