This is an excellent example of a DIY project and educational lesson plan on building a DCBL (Brushless DC Electric Motor) from scratch. The author provides a detailed guide on the process, including materials, calculations, and troubleshooting tips. Here's a summary of the key points: **Project Overview** * Build a simple DCBL motor using neodymium magnets, copper wire, and an Arduino board. * Understand the principles of electromagnetism and how it applies to the motor. * Learn about the advantages of DCBL motors over brushed electric motors. **Skills Learned** * Computing: programming an Arduino board * Computer Science: understanding algorithms for controlling the motor * Electromagnetism: understanding how magnets interact with copper wire * Assembly: building the motor from scratch **Assessment** * Does it work? How close is it to working? * Rubric: + Motion: 80-90% (any motion) + Spinning motion: 100% + Circuitry built and sound, but not moving: 80% **References** * Wikipedia page on Brushless DC Electric Motors * Tesla blog post on Induction vs. DCBL motors **Additional Information** * A DCBL motor is similar to a brushed electric motor but without brushes. * It uses permanent magnets on the axle instead of brushes to switch polarity. * DCBL motors are used in hybrid electric vehicles (HEVs) and battery electric vehicles (BEVs). Overall, this project provides a fun and educational experience for students interested in electronics, electromagnetism, and computer science. The author's warnings about safety precautions and potential hazards are also valuable reminders for anyone working with magnets and electricity.
