Magnet motor in Argentina

[silverdragonrs]

i think the aluminum is a good choice for prototypes but i agree with you jason that the final product should be of the currect materials all things considered. (assuming that your right about aluminum reacting with magnets. i wouldnt know about that.) im using a hard drive disk as my rotor anyone know what they are made of and the reaction to magnets? obviously there is some reaction since harddrives are magnetic storage devices.

Tao,

This is good to hear. I was starting to get a bit depressed. Most of my work is with aluminium.

OK, I didn't want to say too much about my motor until it was complete or working but I would like some input from you. Since you have done quite a few simulations and femms, can you please give me a recommendation on what you think would be best for the rotor.

Let me explain.

The attached picture is of my stator magnets. I am sort of reverse engineering it since I am building it with what I have in stock or available and then drawing them in ACAD. The red area is 1/2" diameter neomag in an aluminium sleeve. There is a steel rod that is inserted into the sleeve and on the opposite side is another aluminium sleeve that will be used as the pivot point. This point is adjustable along the rod. Hopefully I will have the stators mounted tomorrow. I am using 13 stators since thats how many it took to to give me about a 3 1/2" inside diameter. Also sounded like a lucky number.

For the rotor, I will use Teflon or what most of us call, a kitchen cutting board.(P.S., Don't tell Danny, his mother-in-law will kill him). I will cut two 3 1/2" circles to get double the thickness. I have some 1 X 1/2 X 1/8 neo mags to use for the rotor. I will groove the Teflon so that I can wedge the neos between the two pieces.

What I want to ask you is, do you think I should use 2 or 3 mags? Also, since you are looking into a ring for the rotor, would it be beneficial to also place 2 or 3 mags on the opposite side of the rotor in attraction?

i say three (and she can't kill me if we don't tell her) and i would say yes to the attracting mags on the other side to releive stress from the system just keep in mind that your trading magnetic stress for physical stress on the bearing so you may want to double up on your rotor bearings.

thanks (funny guy!)
