Sail Winch (720 degree) Servo Question

erco

Can someone confirm if a Sail Winch (720 degree) Servo rotates its full range using standard 1-2 millisecond pulses? I'm guessing that's the case.

Yes. Look here: http://www.servocity.com/html/hs-785hb_3_5_rotations.html#.VULIEM4mW2Q

Thanks Rich. That's a particularly amazing SW servo doing 3.5 revolutions, so it's a 1260 degree servo.

My guess is it uses a 5 turn pot. I didn't find any 5 turn pots in my quick search of ebay but I saw lots of 10-turn versions.

Depending on the servo, you might need to move some of the electronics to outside the servo if you were to make your own.

IMO, some sort of encoder inside the servo would be a more useful device though not as simple to control.

You fiend! Please don't sidetrack me by suggesting such interesting challenges.

My question was purely academic, good sir.

Or was it?

Mwa-ha-ha-ha-ha...

The sail wench (er, winch -- arrr!) servo I once took apart used a standard 1-turn pot, but just wasn't connected directly to the output. You'd think a multi-turn would be cheaper, but the extra mechanics probably added 5 cents to the cost of making the thing.
