Hi Im looking for some sort of linear actuator for diy chicken coop project with a 200mm travel, and atleast 100mm/s speed, but generally the faster the better, force between 10 and 35lbs(5 to 15kg)
I have looked online and linear actuator all seem to be VERY slow typically 10mm/s but have an excess of force. typically 150kg. belt driven systems seem to be faster but are much more expensive. I would ideally like to avoid a 1:20 lever arm but im not sure what else i can use to get the speed and travel. rc servos seem to not be quite enough 30k/cm is considered high torque. with a servo arm of 20cm and a 60 degree arm it would leave just 1.5kg force at the end. and i'm not sure that would be enough force but would be very fast. w what other options do i have for cheapish(£30-£50) linear motion.
