{"product_id":"b0gqbh3n4w","title":"Shaftless Pump-Push Motor Model, High-Power Brushless Inner-Rotor Motor Electromagnetic Motor, STEM Science Kit for Tech Desk Decor \u0026 Educational Physics Display","description":"\u003cdiv\u003e\n\u003ch1\u003eAbout This\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable Control Module with Multiple Functions: A heat-sink-equipped controller is included, supporting speed adjustment, one-touch braking, and forward\/reverse rotation switching. Clearly labeled switches and potentiometers on the base allow intuitive operation and clear demonstration of different working conditions.\u003c\/li\u003e\n\u003cli\u003eQuality Components for Stable Operation: The stator uses high-temperature oxygen-free copper windings, while the rotor integrates eight strong permanent magnets arranged in alternating polarity. Large-diameter thin-wall deep-groove ball bearings support smooth rotation with controlled heat generation and low mechanical noise during extended operation.\u003c\/li\u003e\n\u003cli\u003eOpen-Structure Coreless Motor Design: Built around an inner-rotor brushless hollow motor structure, the stator coils and permanent-magnet rotor are fully exposed. The shaftless layout allows the magnetic field interaction and rotational motion to be observed directly, making operating principles easy to understand at a glance.\u003c\/li\u003e\n\u003cli\u003eWide Voltage Compatibility and Smooth Speed Control: The system supports a 12–24V input range and includes a 12V 5A power adapter compatible with both 110V and 220V sources. Power consumption is approximately 30–40W, with rotational speed smoothly adjustable from about 100 to 1500 RPM.\u003c\/li\u003e\n\u003cli\u003eIndustrial-Style Base for Demonstration and Display: With overall dimensions of approximately 24 × 16.5 × 15 cm and a weight of around 1 kg, the structure remains stable during operation. The industrial appearance and solid base make it suitable for classrooms, laboratories, exhibitions, and technical displays, with options for customized labeling in bulk orders.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BrightMinds","offers":[{"title":"Default Title","offer_id":47690136715348,"sku":"SPH-B0GQBH3N4W","price":240.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/3590\/1780\/files\/41NF8Boa02L._AC_SL1500_b46cbc98-205e-4f71-85af-4863b661ef3c.jpg?v=1789644956","url":"https:\/\/learnbrightminds.com\/products\/b0gqbh3n4w","provider":"BrightMinds","version":"1.0","type":"link"}
