I am building my first bedini motor. And I mas playing around with the extra magnets and found an intersting idea that I will incorporate into the design. this should make it so it takes less power to run the motor. What I did is simply hold a magnet off to the side of the rotor in a very weak repulsion mode so that it just barely neutralizes the attraction of the other magnets to the core. so the magnets have no sticking point when near the core because the repulsion magnet contacts the attraction to the core so now the wheel freewheels easier. it sholud make it so one can adjust the input power lower and still have the motor run without interfering with any of its other functions.
I am using the ceramic magnets but this maigh be also utilized to reduce the drag on neo magnets.
But on thte other hand it will reduce any torque one might get from the magnets being attracted. but I am under the impression that most of the power comes from the powering up of the coil so we will see. Anyone have thoughts on this?
