Servo question
« on: June 16, 2010, 03:18:54 PM »
Hi guys how do you speed up a servo.? Iv hacked the servo futaba s3001 but seems to be slow. The only thing i did to hack the servo was to take the lug out and i get continous rotation. Am i missing something out or do i need to get a different servo with speed.

My plan is to run the servos using a thread tri track system which im planing to build. I wont some speed but my servos are pretty slow but they do have alot of torque.

You cant really do anything inside the servo to speed it up. Servos are 6V tolerant, so you can bump up the voltage to 6v for a little more speed and torque.

Otherwise you could use bigger tracks or use gears to make it faster.

im using 4.8v so thats probably why the servos are slow. If i opt to a gear type, what kind do i need?

My treads are lego type, size at 1 1/2 inch wide and 60cm lenght. Im going to use 2 of the lego treads but im going to modify them so they have rubber on them for grip.

When you hack a servo, the pulses that used to correspond to position with now correspond to speed. The farther away the pulse is from the center position is, the faster the servo should go. Though don't exceed your servos standard parameters.

so basically use the appropiate power according to your servo ie max 6v for futaba s3001. Would that be enough to generate some speed.

Or would getting a motor gear rc be a better option to get the speed. If so which one should i get.?

Or am i completely looking at the wrong direction.

consider testing if 6v will speed it up. if that dosen't work, consider a getting a gear box.
this is a signature.

i will purchase the 6v battery, but if it doesnt make a difference which gear box should i get. Is there a link you can provide to which type to get.
If a gearbox has a fitting futaba plug that would be great. Just plug and play.
If its more complicated than that any help would be appreciated.
I really want to start my project soon as.
