🌟 Key Highlights
- Ultra-Lightweight Design: Weighing a mere 0.9g with a 4mm diameter frame, this motor is built for space-constrained applications where every millimeter and milligram counts.
- Blazing Fast Speeds: Reaching a no-load speed of up to 59,100 RPM, it provides the swift, low-inertia response that only a coreless (hollow-cup) design can offer.
- Flexible Voltage Range: Optimized for 3V DC but safely operational anywhere from 1.2V to 3.7V DC, making it perfect for single-cell lithium battery or low-voltage setups.
- Low Starting Threshold: Kicks into gear at just 0.8V, ensuring reliable start-ups even under low battery conditions.
🛠️ Ideal Applications
Thanks to its permanent magnet coreless construction, this micro motor provides smooth rotation, minimal electrical noise, and high efficiency (IE 2 class). It is an excellent choice for:
- Kitchen & Household Appliances (mini frothers, blenders, and automated dispensers)
- Personal Care Devices (electric toothbrushes, facial cleaners, and compact massagers)
- Robotics & Aerospace Models (mini drones, RC aircraft rudders, and micro driving systems)
