Default Re: [EVDL] Jumpy Pots

One issue is that the ROTARY MOTION of the BP-6 pots is not normal. Many
"Standard" pots have a 270deg turn from stop to stop... the Curtis PB-6 Pot
has a different range... Substituting a pot with more or less motion will
either cause a very touch throttle (what we are trying to get rid of) or a
throttle that can't reach FULL....

Does anyone know what the rotary motion of the Curtis is? Many of the HE
and rotary sensors can be ordered with different mechanical ranges, you just
need to know what to order...

All of these use the cheapest grade of pot possible. Look at them; they
are the same cheap unsealed $1 pots used in bottom-of-the-line consumer
products for indoor use.

The auto companies have used throttle pots for many years. Despite being
the grand masters of "cheap" :-) they still use better quality pots than
Curtis. Often, they have two or even three pots in parallel, so failure
of one does not cause the system to fail. So, you should be able to use
one from existing cars.

Another option is to use higher quality sealed pots. For years I've used
the Allen Bradley type AB pot to replace the Curtis pot. A 20k pot has
just about the right resistance range (0-5k) when turned over a 90 deg. arc.

Does anyone have experience with the Kelly throttle? See
http://www.newkellycontroller.com/product_info.php?products_id=3D132 . It =
is
available 0-5k ohms or 0-5V. It is a modular unit with pedal and goes full
range in 36 degrees. It looks weatherproof and I am planning to use one on
my lawn tractor conversion.

Try MIL style RV4. There are many manufacturers (like the Allen Bradley
type AB I mentioned, though Allen Bradley seems to have sold their pot
business to someone, so it's under a new name). Here's an example from
Digikey:

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=RV4N253C-ND
http://www.precisionelectronics.com/MIL%20Style%20RV4%20PDF%20Download_files/MIL%20Style%20RV4.pdf

Sealed, gold plated terminals, stainless steel shaft, 25,000 cycle
rotational life, about $8.

Thank You, Lee!

A great no BS answer! JUST ordered TWO ,to reserect the pot boxes I have
kicking around with bum pots! 25k service factor SHOULD lastawile in my
Electrac AND car!Well, the Sentra I sold, with a Curtis, I'll KNOW he'll be
needing a pot, too? I like 8 bux, better than 50-70 anyhow!

Default Re: [EVDL] Jumpy Pots

When you say 75deg, is that 75 real, as in less than 1/4 turn, or is it 75deg which is really 150deg or a bit less than 1/2 turn?

I have been able to find a few 90deg HE pots, and a few more 150deg...

I was also able to find a 90deg SEALED, IP rated, molded connector thingy that looked interesting... but I get concerned when they start saying electrical vs mechanical movement, etc...
