Fwd: eddy current brake

[Peter Juergens]

Hi there,

think the Eddy.effect is exlained enough, so lets go back where the idea came 
from (can't remember who it was, but what it was):
reducing/removing backlash of the ignition rotor!
IMO, the ign rotor is a very good place to get the signals from, its (most of 
the times)good accessable and you don't have to bore holes into the engine 
block or clutch housing to gain acces for the sensor.

Back to Eddy. :-)
Someone mentioned, the higher the RPM the higher the drag. In fact, thats 
right, but only for a constant magnetic field.
What would you guys think about using an AC driven E-magnet (no experience 
yet, only thinking about) with frequency varying over RPM, in order to 
establish a (nearly) constant drag over the RPM range?

If you find this could be from interest, think of it...
