Magnet motor in Argentina

[silverdragonrs]

I figured out how to cut magnets

it is a lot like cutting glass. scar the magnet pretty good on both sides and break. then use a file to smooth it out. don't use impact (a hammer or such) to break it as impact often weakens a magnet if not ruining it all together. just keep scarring it untill you can break it with your hands. as for really thick magnets i have not tryed (dont have any) this technique has worked every time for me on magnets up to 1/2 inch thick so far. if you are trying to create an angled cut just use the file or use a dremel. the seperation/cut has to be fast becuase once you cut it through then the oposing poles will cause stress and often cause breakage.

the rotor cap lid is simple to make

use the bottom of a pop can (aluminum is nonmagnetic i think... havent checked) then use a rubber malet and a round pipe to shape the curve. use a file on the edges

not very scientific but it will work.

tao.... and for those of us who did not attend harvard that means.......

sorry to be more specific.... i can figure out some of that but to begin with could you give me a basic breakdown of what 5Nm is and means and compare it to something common

also what is the aprox HP of this device based on your present figures and are those rpm's reasonable.... I don't know what the average rpm of an electric motor or anyother motor is so i have nothing to compare your figures to.

sorry for all the trouble guys i do not have the education you all appearently have. and as i said i am just beggining in this feild of study. i hope i am not getting on your nerves i know how it can be....

tao, thanks a lot for the FEMM graphs and for the calculations. Sounds very promising. Will have to understand better the FEMM program, however, and what the optimum model would be.

So, tao, the tendencies so far in the design are to have a whole round rotor magnet, magnetized along the diameter, as in your Bryce drawing (the one with parts made of wood) and rectangular stator magnets. This would provide a better torque than the design with the three (or four) separate rotor magnets, correct?
