btnx Low power high-speed rotating wheel scientific desktop toy - small Hall effect motor 7P3H9

Description:This compact motor model showcases the fascinating principle of electro drive. It operates using a Hall-effect sensor combined with a drive circuit. Its ingenious design requires only a single coil to function.How it works: When the magnet on the wheel approaches the Hall sensor, the sensor triggers a signal. This signal drives a transistor to switch on and off, causing the coil to generate an alternating field. This field alternately attracts and repels the magnet, creating continuous motion that spins the wheel.Powered conveniently via its built-in Type-C port with just 5V DC (common phone charger compatible), the wheel spins swiftly and smoothly. It serves as both an engaging demonstration of basic physics and a unique, kinetic tech decor item for your desk, shelf, or classroom.Specifications:Product Name: Hall Effect Motor ModelModel Type: Scientific Demonstration / Kinetic Tech OrnamentRotating Wheel Diameter: 10 cmOverall Product Dimensions: 100 x 117 x 48 mm (LxWxH)Operating Voltage: DC 5VInput Interface: Type-C USBPrimary Material: Plastic & Electronic ComponentsFeatures:Compact & Efficient Design: Utilizes a Hall sensor and drive circuit principle with a single coil, achieving rotation with minimal components.Easy to Power & High Speed: Low starting voltage.
