I am testing the results of a small magnet turning a 8 inch rotor. The motor simply spins the small magnet causing the poles to rotate. You can see the motor is small and is a low current motor. I chose this motor because it generates power when rotated better than the other motors I have. It will generate 4 volts just with a small spin with your fingers. |

You can see the full view of the rotor and the field magnet. You will notice the inside of the rotor is full of magnets. They are not part of this test. It is easier to mount the motor to the outside of the rotor. The inner magnets do act as weight for the flywheel effect my test require. |

You can see the miniature magnet spins the rotor quickly. This is
no more than a magnetic gear. This test is not for that. I am testing harmonics
between the small magnet and the rotor magnets.
So the question is this : Will the rotor spin at a 1:1 ratio or will it find a harmonic of the field magnet? |
