Study Notes

Electromechanical Devices

An electromechanical device is a device that uses both electrical and mechanical systems to perform a function.

Sensors and Actuators

A sensor detects and measures physical or environmental parameters, such as temperature, pressure, or light, and converts them into electrical signals.
An actuator uses electrical energy to produce mechanical energy, such as movement or force, to perform a specific task.

Transducers

A transducer converts one form of energy to another, such as converting electrical energy into mechanical energy or vice versa.

DC Motors

A DC motor converts electrical energy into mechanical energy.

Functions and Differences

The primary function of a sensor is to detect and measure physical or environmental parameters and convert them into electrical signals.
The primary function of an actuator is to use electrical energy to produce mechanical energy, such as movement or force, to perform a specific task.
The primary function of a transducer is to convert one form of energy to another.
The main difference between a sensor and an actuator is that a sensor detects and measures parameters, while an actuator produces mechanical energy to perform a task.
