How to choose actuators for an application

It is always very important to choose the right actuators/motors for your machine design. Though very tempting to design a machine leaving the controls to the electrical engineer to figure out, it will not really work. The choice is tightly linked with the mechanical design and functional requirements of a specific machine. In this topic we will try to demistify this choice and cover a large number of actuators used in most common devices.
