What are DC motors used for?

I. Introduction to DC Motors

Before delving into the applications of DC motors, let's briefly review the fundamental principles and characteristics of these motors.

Working Principle

DC motors operate based on the interaction between magnetic fields and electric currents, resulting in the conversion of electrical energy into mechanical motion. This conversion is achieved through the interaction of a stationary magnetic field (stator) and a rotating armature with an electric current.

Types of DC Motors

DC motors can be broadly classified into two main categories: brushed DC motors and brushless DC motors (BLDC). Each type offers distinct advantages and is suitable for specific applications.

II. Applications of DC Motors

DC motors find extensive use in a wide range of applications due to their favorable characteristics and precise control capabilities. Let's explore some of the prominent fields where DC motors are employed:
