Advantages of Electric Actuator | disadvantages of Electric Actuator

This page covers advantages and disadvantages of Electric Actuator. It mentions Electric Actuator advantages or benefits and Electric Actuator disadvantages or drawbacks.

Introduction

• Transducer is a device which converts one form of energy into the other form of energy. Both sensor and actuator are energy conversion devices. Hence they can be called as transducers.
• A sensor is a device which converts physical parameter to electrical output.
• An actuator is a device which converts electrical input signal to mechanical or physical output signal (e.g. force or displacement).

Following are the main types of actuators.
• Electric actuator
• Hydraulic actuator
• Pneumatic actuator

What is Electric Actuator?

• It is one type of motor which is responsible for moving or controlling a system or mechanism in which it is installed. It can generate motion and also it can stop motion.
• It is operated by source of energy which is elecric current.
• It converts this energy into motion.
