Pneumatic Actuator vs. Electric Actuator: A Comprehensive Comparison
Release date：2025/6/23
In industrial automation, actuators play a crucial role in converting energy into mechanical motion. Two of the most widely used types are pneumatic actuators and electric actuators. Each has distinct advantages and limitations, making them suitable for different applications. This article provides a detailed comparison of these two actuator types based on performance, efficiency, cost, and application suitability.
1. Working Principle
Pneumatic Actuator: Uses compressed air to generate motion. When air pressure is applied, it moves a piston or diaphragm, creating linear or rotary motion.
Electric Actuator: Converts electrical energy into mechanical motion via an electric motor, often with gears or lead screws for precise control.
