DC Motor in IoT: Types, Working, Applications, and Integration Guide [2025 SEO Optimized]

Device Overview

Introduction

A DC motor (Direct Current Motor) is an electromechanical device that converts direct electrical energy into mechanical rotation. Widely used in automation, robotics, automotive systems, and industrial equipment, DC motors are known for their precision control and ease of integration.

This guide offers everything you need to know about DC motors—how they work, their types, features, and real-world use cases—structured for optimal SEO performance and AdSense approval.

What is a DC Motor?

A DC motor is a type of electric motor that runs on direct current (DC) electricity. It works on the basic principle of Lorentz Force, where a current-carrying conductor placed in a magnetic field experiences a force that causes motion.

How Does a DC Motor Work?

The key components of a DC motor include:

  • Stator (Magnetic field provider)

  • Rotor / Armature (Rotating part)

  • Commutator (Switching current direction)

  • Brushes (Transfer current to the armature)

  • Power Source (DC power supply)

Working Principle:

  1. DC current flows through the armature windings.
  2. The magnetic field from the stator interacts with the current.
  3. This generates torque (rotational force) on the rotor.
  4. Commutator and brushes reverse the current direction to maintain continuous rotation.

Types of DC Motors

Here are the major types of DC motors used across industries:

1. Brushed DC Motor

  • Uses carbon brushes and a commutator.
  • Simple, cost-effective, but requires maintenance.
  • Applications: Toys, small fans, automotive applications.

2. Brushless DC Motor (BLDC)

  • Uses electronic commutation (no brushes).
  • Higher efficiency, quieter, low maintenance.
  • Applications: Drones, electric vehicles, hard drives.

3. Shunt-Wound DC Motor

  • Field winding is connected in parallel to the armature.
  • Provides stable speed at varying loads.
  • Applications: Lathes, conveyors.

4. Series-Wound DC Motor

  • Field winding is in series with the armature.
  • High starting torque.
  • Applications: Cranes, elevators, winches.

5. Compound DC Motor

  • Combination of series and shunt windings.
  • Balanced characteristics.
  • Applications: Rolling mills, presses.

Technical Specifications of DC Motor

Parameter Description
Voltage Range 3V – 48V (typical)
Current 100 mA to several Amps
Speed 100 – 10,000 RPM
Torque Low to High (depends on type)
Efficiency 70% – 90% (BLDC higher)
Control Method PWM, H-Bridge, ESC (for BLDC)
 

Benefits of Using DC Motors

  • Precise speed control
  • Quick start, stop, and reverse
  • Cost-effective for small and medium loads
  • Compact and lightweight
  • Easy to integrate with microcontrollers

Applications of DC Motors

DC motors are widely used in:

  • Electric Vehicles

  • Robotics and Automation

  • Consumer Electronics

  • Industrial Machines

  • Home Appliances

  • Medical Equipment

  • Solar Tracking Systems

  • Automatic Doors and Gates

Example: DC Motor Controlled Using PWM

Here’s a simple example using an Arduino to control a DC motor with PWM (Pulse Width Modulation).

Components Required:

  • DC Motor (6V or 12V)
  • Arduino UNO
  • L298N Motor Driver Module
  • Power Supply (Battery or Adapter)
  • Jumper Wires

Circuit Diagram:

  • Connect DC motor terminals to L298N OUT1 and OUT2.
  • L298N IN1 and IN2 to Arduino digital pins 8 and 9.
  • ENA pin of L298N to PWM pin 10 of Arduino.
  • VCC to 12V, GND common with Arduino.

Arduino Code:

int ENA =10;  
int IN1 =9;
int IN2 =8;

voidsetup() {
    pinMode(ENA, OUTPUT);
    pinMode(IN1, OUTPUT);
    pinMode(IN2, OUTPUT);
}

voidloop() {
    digitalWrite(IN1, HIGH);
    digitalWrite(IN2, LOW);
    analogWrite(ENA, 150); // Speed control (0–255)
    delay(5000);

    digitalWrite(IN1, LOW);
    digitalWrite(IN2, LOW);
    delay(2000);
}

✅ Output:

The motor will run forward for 5 seconds at medium speed and then stop for 2 seconds, repeating the cycle.
