Summary of Introduction to Actuators Presentation

00:00:00 - 00:05:00

This video provides an introduction to actuators, explaining what they are, their uses, and their various classes. Actuators are devices that create motion and are used in a variety of applications. Electric actuators use current to create a magnetic field that rotates a shaft, while mechanical actuators use a rotary motion to produce linear motion. MEMS actuators use natural oscillations to move an object.

• 00:05:00 This video explains the basics of electric actuators, which are used to create motion. Electric motors work by using current to create a magnetic field around a coil, which in turn rotates the shaft. Reverse current flow through the actuator causes it to rotate in the opposite direction. Mechanical actuators, such as screws and jacks, use a rotary motion to produce linear motion. MEMS actuators, such as resonators, use natural oscillations to move an object. These devices are often used in micro systems, where low forces are needed.
