Motor Field Weakening Demo Kit with Arduino Uno + Motor
Motor Field Weakening Demo Kit with Arduino Uno – Extend BLDC Speed Beyond Rated RPM
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a real-time motor control system that pushes a brushless DC motor beyond its rated speed using field weakening — a critical technique in electric vehicles and industrial drives. You'll program an Arduino Uno to modulate ESC signals while monitoring current and rotor position, then watch RPM soar beyond base speed on the OLED display. It's a hands-on deep dive into advanced motor control that brings classroom theory to life.
What You'll Build
You'll assemble a fully functional field weakening demonstration: a 2204 brushless motor driven by an ESC, with an AS5600 magnetic encoder tracking rotor angle, an INA219 measuring current, and an Arduino Uno executing the field weakening algorithm. The OLED shows real-time RPM and current draw, allowing you to tune parameters and visualize speed extension.
What You'll Learn
- Write a field weakening algorithm to extend BLDC speed beyond rated RPM
- Read high-speed rotor position from an AS5600 encoder over I2C
- Monitor motor current and voltage using the INA219 module
- Analyze torque-speed characteristics before and after field weakening

Who This Kit Is For
Designed for CBSE Class 11-12 students delving into advanced motor physics, first-year B.Tech ECE/EEE students exploring embedded control, and ATL Tinkering Lab participants eager for a competitive-edge project. If you're preparing for a Smart India Hackathon or a college technical exhibition, this kit delivers measurable, real-world outcomes.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Access the AI companion via the QR code on the box; it knows this exact wiring and code. You can also message our WhatsApp support for live troubleshooting.
Can I test the field weakening effect without a load?
Yes, you'll observe RPM increase on the OLED when the algorithm engages, even with no external load. The INA219 current drop confirms reduced torque.
Is the AS5600 encoder accurate enough for field weakening control?
Absolutely. The 12-bit magnetic encoder provides precise rotor angle feedback over I2C, essential for synchronizing the field weakening commutation advance.
Will this kit help with college projects or hackathons?
Definitely. The motor control principles you learn map directly to EV powertrain and drone projects, making it a strong foundation for B.Tech final year projects or Smart India Hackathon submissions.
