[6-Week Course] Practical Embedded Project Learning with Electric Scooters

This is a course where you can learn circuit/PCB design, STM32 firmware, and BLDC motor control all at once. In this course, you will design a 3-phase inverter yourself and use it to drive an electric scooter. A 6-week challenge program will be conducted, allowing you to improve your skills through weekly missions.

[New Video] Why Do DC Motors Rotate? From Their Structure to Operating Principles

Hello, this is Control Geek.

I’ve uploaded a new video covering the structure and operating principles of DC motors.

When first studying DC motors, many people connect an MCU to a driver like the L298N and practice
forward, reverse, and PWM control first.

However, if you later want to study BLDC or PMSM control,
it is important to first understand how current and magnetic fields inside a motor generate force and why rotation occurs.

In this video,

  • Basic Structure of a DC Motor

  • The Role of Brushes and the Commutator

  • The Principle Behind Torque Generation by Current and Magnetic Fields

  • Why a motor can keep rotating in one direction

I’ve organized it as intuitively as possible, together with animations.

Those of you taking the course may also find it helpful to watch this casually as a way to review the most basic principles of motor control.

Please give the new video lots of views as well!
