I have been working on improving a motor design which I came up with some years back. The idea of this motor design was to mostly use the flux of powerful Neodymium Magnets we now have, since in a standard magnet motor we would not get a power gain just by upgrading the old ceramic magnets to Neodymium Magnets, as we would also have to add more power to the motor coils to overcome the extra attraction force the Neo Magnets have. However, in my motor design there is no sticky spot, so the more flux the magnets have the more mechanical power the motor has without changing the input power.
I have made a new video which demonstrates this and also demonstrates a better magnet and cores position which takes full advantage of both Permanent Magnet Poles and of the Electromagnet Poles.
This improvement basically double the mechanical output power of my first design without any increase to the input power.
Hi Luc 1kg per watt-now that would be usful indeed. I have never worked out how much energy would be required to lift one kg. I know it takes 9800 joules of energy to lift 1 ton up 1 meter. What is interesting about that is a heavy duty AA battery has about 9480 joules of energy stored within it.So we can just about raise 1 ton by 1 meter using a AA battery.
