That was a very good call Fechter
Do you think that we can use the same effect to do the opposite ?
I mean, changing the lower magnet field to make the throttle
signal curve more progressive.
Hmm... now that might be easier with a microprocessor.
Actually, you could probably mess with the magnetic field to get that effect. I think the way to do it would be to make the high side magnet thinner so it has less dipole moment. Making it weaker might have a similar effect, but it still needs to make the hall sensor go full throttle
, so you can't weaken it too much.
If you remove the high side magnet and replace it with a thinner one, you could vary the spacing of the magnet such that it just reaches full throttle
when you fully advance it. Slightly angling the magnet will change the response too. A drawing would be good here. It's very easy to bench test though. You could probably get away with a 9v battery and a voltmeter. A 5v supply would be better since that's what the throttle
normall runs off.
I'll have to think about it, but there may be a way to place some iron in the magnetic path to get a more progressive low end using the stock magnets.
