Big Bearing Outer Rotor BLDC Motor Model High Speed Hall Sensor Physics Science Toy
Hero Section: Industrial Art in Motion
There is a raw, mechanical beauty in a massive bearing spinning effortlessly. This Big Bearing Outer Rotor BLDC Motor is a celebration of that aesthetic. Centered around a colossal 95mm industrial bearing, this model strips away the housing to reveal the heart of electromagnetic propulsion. Powered by modern Type-C technology and driven by a smart Hall sensor system, it transforms electrical energy into a silent, high-speed blur. It is heavy, precise, and undeniably cool—the ultimate kinetic sculpture for your desk.
Why Choose This Outer Rotor Model?
- The "Big Bearing" Aesthetic: The centerpiece is a massive Model 6518 Bearing with a 95mm outer diameter. This isn't a toy part; it's an industrial component that provides incredible stability and a satisfying, heavy-duty visual impact as the outer rotor spins around it.
- Modern Type-C Power: Say goodbye to clunky proprietary adapters. This motor features a Type-C interface, allowing you to power it with standard chargers. It supports a wide voltage range (5V-20V), giving you control over the speed simply by changing the input voltage.
- High-Efficiency Coreless Coils: Unlike standard motors with iron cores, this model uses Coreless Coils. This design eliminates "cogging" (magnetic resistance), resulting in smoother acceleration, higher efficiency, and less heat generation.
- Transparent Engineering: With its open-frame design made of acrylic and copper, every component is visible. You can see the 10 strong magnets interacting with the coils, making it a fantastic educational tool for understanding Brushless DC (BLDC) motor principles.
Technical Highlights: Under the Hood
- Outer Rotor Design: Unlike standard motors where the shaft spins inside, here the outer shell spins. This design provides higher inertia and torque, maintaining stable rotation at high speeds (up to 2000 RPM).
- Hall Effect Drive: A new generation Hall Drive Board detects the rotor's position and electronically switches the coils. This brushless system ensures a long service life with zero friction from mechanical brushes.
- Magnetic Propulsion: Ten powerful magnets (20x10mm) interact with two precision-wound coreless coils (22x12mm) to generate the Lorentz force that drives the massive rotor.

Usage Scenario: The Desktop Dynamo
Plug it into your laptop or a USB wall charger. Press the start button. The large outer ring begins to rotate, accelerating into a silent, stable spin. The switch indicator lights glow, adding a high-tech vibe. It’s a mesmerizing background gadget for your workspace, perfect for moments when you need to zone out and refocus.
Important Tips:
- Voltage Recommendation: While the motor supports up to 20V, we highly recommend running it at 12V or below for extended periods to prevent the coils from overheating.
- Starting: Due to the heavy rotor inertia and single-phase drive, the motor may require a gentle manual spin to get started after pressing the button.
- Handling: The acrylic structure is precise. Please handle with care and avoid dropping the unit.
