Product Specifications:
Color: As shown
Material: Acrylic
Power Supply: 5V–24V
Current: 1A–5A
Rotational Speed: 20,000–50,000 RPM

Product Features:
1. [Magnetic Levitation Bearing + Hall Brushless Motor for Ultra-Low Friction, High-Speed Operation]
This device utilizes an advanced magnetic levitation support system; the rotor spins while fully suspended in mid-air, completely eliminating the physical friction found in traditional mechanical bearings. Paired with a precision Hall brushless motor drive system, it achieves exceptionally smooth and quiet operation. It allows for a clear, intuitive demonstration of magnetic levitation technology and brushless motor principles, even without a vacuum.
2. [Innovative Vacuum Design to Break Speed Limits]
The unit features a specially designed, highly sealed one-way vacuum valve (with a dedicated evacuation port). Evacuating the internal air using the included tool drastically reduces air resistance. In a vacuum environment, the rotational speed can soar to an astonishing 20,000–50,000 RPM, pushing the motor's performance to the limit and delivering a stunning visual experience.
3. [Wide Voltage Range (5V–24V) & Easy Speed Control]
The product supports a wide DC input range of 5V to 24V and currents of 1A–5A. You can test it using a standard mobile phone charger or power bank (5V startup) or connect it to a professional laboratory power supply (24V) to unlock peak performance. A built-in speed control knob allows you to easily adjust the RPM and observe changes in speed and centrifugal force across different voltages and currents—making it ideal for physics experiments involving variable parameters.
4. [Fully Transparent Body & Handheld Design for Immersive Centrifugal Force Experience]
Constructed with a highly transparent acrylic tube and stand, the device offers a clear view of the precision rotor, magnetic poles, and internal structure. Thanks to precise dynamic balancing, the unit remains safe to hold and observe at close range even at ultra-high speeds (20,000–50,000 RPM); holding the base is recommended. As it spins at high speeds, you can clearly feel the immense centrifugal force; the interactive experience created by this physical phenomenon is intensely visceral—a tangible sensation that textbooks simply cannot replicate.
5. [High-Tech Desktop Ornament & Hardcore Educational Tool: Explore the Mysteries of Physics]
This device is not merely a sophisticated, high-tech desktop ornament; it is also an exceptional STEM physics teaching aid. It offers a vivid, hands-on demonstration of complex physical concepts such as magnetic levitation, electromagnetic induction, brushless motor principles, centrifugal force, and fluid dynamics (including vacuum drag reduction). Whether displayed in a science museum, used in a school laboratory, or given as a creative birthday gift to physics enthusiasts, engineers, or young science buffs, it is sure to ignite a passion for scientific exploration.
