Electric Actuators
An electric actuator is a device that converts electrical energy into mechanical motion, either linear or rotary. Unlike pneumatic or hydraulic actuators, they don't require compressed air or fluid, which makes them a cleaner, more precise, and energy-efficient solution for automating machinery.
How They Work
An electric actuator uses an electric motor to create motion. The motor's rotation is converted into the desired motion using a transmission mechanism, such as:
Linear Actuators: These convert the motor's rotary motion into a straight-line push or pull. They commonly use a ball screw or lead screw, which is a threaded rod that a motor rotates. A nut on the screw moves along the rod as it turns, extending or retracting a piston rod.
Rotary Actuators: These convert the motor's rotation directly into a controlled rotary motion. They are used for applications like operating valves that require a precise turn.
Many electric actuators also include a control system with a feedback mechanism (like a position sensor or encoder) to ensure accurate and repeatable positioning.
