Mostly Permanent Magnet Motor with minimal Input Power

[synchro1]

Rectangular core Halbach electro-magnet. Packing square 3d printed coil forms with ferrite composite epoxy would improve the building process. These coils were designed for levitation bearings:

Mechanical screw

Inserting half a screw thread collar in the core of the diametric tube magnet would permit a turnkey bolt to rotate it half way as it compressed. If the attraction force of the Halbach arrays were greater then the force the 2 diametrics would require to roll over, it might run as a mechanical perpetual motion machine; Only if those forces proved to be unequal!

Here's a video with the spiral and key kind of action:

tripling the stators may help;

The oscillator needs a spring loading mechanism that snaps the diametric around like the wheel in this video:
