We made a model of the Perendev according the patent.
We only used one wheel instead of three as described in patent.
The magnet position between stator and rotor is adjustable by means of three
identical segments placed on stator. Neodymium magnets (Ø-10mm, h-10mm, grinding
angle 30°) are placed in graphite case with plate of magnetic screening material.
At best adjustment of stator segments; the rotor is moving easily, but stops after several rotations.
At worst adjustment; can move rotor very hardly. The problem seems to be in big gap between rotor magnets.
Now we are working at linear version of device.
