716 Coreless Vibration Motor – 3V

The 716 Coreless Vibration Motor is a compact DC micro motor designed for vibration and haptic feedback applications. It utilizes a coreless rotor structure that eliminates iron core losses, resulting in improved efficiency, faster response, and smoother operation. Operating at 3V with a high speed of 18000 RPM, it provides reliable and consistent vibration performance. Its lightweight and miniature cylindrical design make it suitable for integration into space-constrained devices. Ideal for wearable electronics, mobile devices, tactile feedback systems, and small embedded projects.
