How Does an Electric Actuator Work?

An electric actuator is a type of mechanical device whose purpose is converting electricity into kinetic energy through a rotary motion. This automates the machinery operation to improve the complexity and efficiency of the process.

Electric actuator designs are based on specific tasks they complete in the processes they are meant to be used for. These can also vary in terms of size and dimension.

Electric actuators are now used for different applications because of the current shift toward the substantial increased decentralization happening in today’s automation technology.

Modern electric actuators also feature new process controllers, making it simpler to adhere to the latest updated standards on automation.

The use of electric actuators has also become safer and more secure than ever made possible by the dependable capabilities preserving the control of the user over the process even when a power loss occurs.

How Do Electric Actuators Work?

The electric motor creates rotary motion while the rotor or spindle rotates. This motor spindle is directly paired to the helical screw through the drive shaft and in turn, this will rotate in the ball screw nut.

While the spindle is in rotation, the ball screw nut is driven either backward or forward along the helical screw. The ball screw nut has a hollow piston rod attached to it that forms the linear motion into or out of the linear actuator while the motor rotates counterclockwise or clockwise.

An electric drive controls the motor that allows variation of the rotation speed and the actuator’s linear speed as a result. A feedback mechanism provides positional information. The linear actuator could be programmed into moving to a specific position, stop, and move on, or go back to its rest position.

The motor’s power will determine the generated torque as well as the force that could be put into useful motion with the help of the actuator.
