[NewCandle] "jerk" motor

[Keith Nagel]

If I understood correctly from the link, Nicks motor
is frequency controllable and about as good a test
bed as you'll get. He would have to modulate the
freq, which may not be possible with the "out of the box"
controller, I don't know. But to see the effects I
am aluding to you would need to resonate the output.
Otherwise it's just a field mill. I'm not suggesting
he'd seeing OU, just that modulation can drive a lot
more energy into the resonance than what you might
intuitively think. 

That said, I agree that old hard drive motors are handy
things. I've used them with their frames and controllers,
what you want are units that automatically spin up the
drive. Some don't, or they shut down after a few 10's of
seconds searching vainly for data. But many just keep
going, and then you have a nice motor with a mount for discs.

BTW - small high speed motors are usually fairly expensive but the 
newer generation of hard disks have motors that spin at 7500 to 
10000 RPM using only a few watts. Sometime you can pick these up 
for free if the circuitry is bad, and they are easy to canablize.

Recently on eBay I bought an external backup USB drive - 180 GB 
for about 50 bucks. It can back-up my entire PC 160 GB drive I 
bought last year - and in amazing time. It blows me away how 
qyickly the cost has come down on these since, my first 100 
megabyte drive (actually 96 megs but a very big deal back then) 
which was over $1000 - and I was happy to pay that at the time 
(early 90's) !!!

Let's see 1,800 times more capacity for 20 times less money.
