The Ultimate Guide to Actuators

In an era where automation is revolutionizing every industry, actuators are at the heart of this transformation. From industrial machinery to DIY projects, actuators play a critical role in providing the precise movements needed to accomplish complex tasks. If you're looking to understand everything about actuators, especially electric linear actuators, you've come to the right place. FIRGELLI Automations is here to guide you through the fascinating world of actuators.

What is an Actuator?

An actuator is a device that converts energy into motion. This energy can come from various sources such as electricity, hydraulic fluid, or air pressure. The key function of an actuator is to create motion or control a system. This motion can be either linear (moving in a straight line) or rotary (moving in a circular path).

What is an Actuator?

Types of Actuators

  1. Electric Actuators:
  • Linear Actuators: These actuators convert rotational motion into linear motion. They are ideal for applications requiring precise control over movement.
  • Rotary Actuators: These actuators provide rotary motion and are commonly used in applications like valve control.
  1. Hydraulic Actuators:
  • Linear Hydraulic Actuators: Use hydraulic fluid to create linear motion, suitable for high-force applications.
  • Rotary Hydraulic Actuators: Often used in heavy machinery, these actuators convert hydraulic energy into rotary motion.
  1. Pneumatic Actuators:
  • Linear Pneumatic Actuators: Utilize compressed air to generate linear motion.
  • Rotary Pneumatic Actuators: These actuators use air pressure to create rotary motion and are simpler compared to their hydraulic counterparts.

Key Benefits of Electric Linear Actuators

Electric linear actuators, like those offered by FIRGELLI Automations, bring several benefits to the table:

  1. Precision and Control:   Electric actuators provide precise control over movement, which is crucial in applications that require exact positioning.
  1. Low Maintenance:   Unlike hydraulic and pneumatic actuators, electric actuators require minimal maintenance, reducing downtime and operational costs.
  1. Energy Efficiency:   Electric actuators are more energy-efficient, converting electrical energy directly into mechanical motion without the need for compressors or pumps.
  1. Easy Integration:   These actuators are easy to integrate with modern control systems, making them ideal for automated industrial processes.

How Electric Linear Actuators Work

Electric linear actuators convert the rotational motion of an electric motor into linear motion. This is typically achieved through mechanisms such as lead screws or ball screws. Here’s a step-by-step breakdown of how FIRGELLI's electric linear actuators work:

  1. Motor Activation:   When activated, the electric motor begins to rotate. These rotary DC or AC (but mostly DC) are free torotate in either direction. The direction dictates the direction of the Actuators movement direction. To reverse the direction you simply reverse the polarity of the electricity to the motor. 
  1. Screw Mechanism:   In an electric linear actuator, the motor's rotary motion drives a threaded screw, such as a lead screw or ball screw. Since DC or AC motors typically run at thousands of RPM with low torque, gears are attached between the motor and the screw to reduce the speed and increase the torque. This gear reduction process makes the motor's high speed and low torque more manageable, enabling the actuator to produce a useful speed and force for linear motion.
  1. Linear Motion:   The rotation of the screw translates into linear movement, causing the actuator's rod to move in or out depending on the motor's direction. The pitch of the screw affects the speed and force of the rod, with different pitches providing variations in these parameters.. 
  1. Controlling the end stops:   Electric linear actuators are equipped with two built-in micro switches designed to stop the motor when the actuator's rod reaches the end of its stroke, either fully extended or fully retracted. These micro switches act as safety mechanisms to prevent the actuator from overextending or over-retracting, which could cause damage to the actuator or the system it is integrated with. When the rod reaches the end of its designated stroke, it triggers one of the micro switches, which immediately cuts power to the motor. This ensures that the actuator stops precisely at the end points, protecting the internal components and maintaining the accuracy and longevity of the device.

Choosing the Right Actuator

Selecting the right actuator can be a daunting task given the variety of options available. Here are some factors to consider when choosing an actuator for your application:

Load Capacity

Determine how much weight the actuator needs to move. FIRGELLI's actuators come in various load capacities to suit different needs from 1bs force to 2,200 lbs force

Speed

When selecting an actuator, consider the speed at which you need it to move. High-speed actuators are ideal for applications requiring quick movements, while others may prioritize force over speed. It's important to remember that speed and force trade off against each other. A high-speed actuator will typically have lower force, whereas a low-speed actuator will have higher force. This is due to the gear reduction inside the actuators, which is designed to achieve one of these attributes at the expense of the other.

Stroke Length

This refers to how far the actuator needs to extend or retract. FIRGELLI offers actuators with varying stroke lengths to accommodate different requirements.

Environment

Consider the operating environment. For harsh conditions, choose actuators with high IP ratings for protection against dust and moisture.

Control System

Ensure the actuator is compatible with your existing control system. FIRGELLI's actuators are designed for easy integration with modern control systems.
