Folks, I just don’t know were to start with this whole article. I has so many misstatements and half truths.
First of all I want you folks at FR that I have been involved with this industry for 22 years and have designed many of the motors and systems that they talk about.
I is not hard nor rare to build these magnets. There are some tricks that you need to know. One: unless they are properly combined with a Getter material they will rust and lose power. Two: unless specifically treated the will when they get to around 140C become demagnetized. This is what the special process that they talk about that has the patents. Patents BTW can be revoked at ANY time by the Congress. This right comes straight from the Constitution.
So don’t Panic. Other materials can also be used such as Samarium Cobalt that will offer almost the same Magnetic Coercively (how’s that for a fancy word ?) .
Note Neo Magnets are available on E-bay but don’t let your kids play with them as the can be dangerous.
should read coercivity
Welcome aboard, we need reasonable minds here.
As those of us know who use Astroflight brushed electric motors.
Then why aren't we using samarium cobalt instead of reliance upon COMMUNIST China?
(Just as a matter of interest: does your keyboard sometimes omit the letter "t"?)
