The linear actuator does the “linear” movement. How do I search for “motor that does the circular movement”? for example to bend an arm of a robot

Hi @lupus and welcome to our forum.
So you actually need rotary movement? Rotary motor?
Since you want motor for a robot, you should buy a servo motor.
Here is where you can have a look: https://www.robotshop.com/ca/en/servo-motors.html

In the application to an arm bending, the bend happens in both directions. But, if I for example take a look at this servo motor https://www.robotshop.com/ca/en/hitec-hs-422-servo-motor.html it says it rotates only in one direction. So it would bend the arm, but will not bend it back. So, the question is still open.
