I know I can find this in Alibaba. They are called line actuators. They work as the scheme below. A shaft moved by a motor that does forward and backwards movement.
The problem is that all of those (below on the right) are for industrial use, heavy duty and expensive. I need something like that cheap, low power, low torque and even in plastic if possible like for toys use.
Does anyone have any idea where should I go?? How would I call it???
Thank you, thank you so much for any help with this!!!
Depeinding on your use and your mechanical abilities, it’s also not THAT hard to build one. A motor, a screw, and a bolt that fits the screw are the essentials.
