Mini Vibration Motor Disc – 3 V DC Coin Haptic Motor
This compact, disc‑shaped actuator delivers a strong, controllable vibration in a footprint no larger than a quarter. Powered by a low‑voltage 3 V DC source, the motor snaps onto a PCB or breadboard, making it ideal for rapid prototyping of tactile feedback, wearable devices, robotics, and interactive art projects. Its integrated eccentric weight creates a smooth, consistent buzz that can be turned on, off, or modulated with simple PWM signals, giving students a hands‑on way to explore electromechanical motion.
With this motor, learners will discover how electrical energy is transformed into mechanical vibration, practice circuit design and programming (Arduino, Raspberry Pi, micro:bit), and experiment with feedback loops for haptic interfaces. Key features include: 3 V operation, 1.6 mm thickness for ultra‑low profile builds, built‑in shaft‑less design for easy mounting, low current draw (≈30 mA idle), and a robust metal housing that withstands repeated use. Its simplicity and versatility make it a perfect entry point for STEAM curricula, encouraging students to blend science (magnetic fields, resonance), technology (microcontroller control), engineering (mechanical design, system integration), art (interactive installations), and mathematics (calculating duty cycles and vibration frequency).
