About This

• Adjustable 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.
• Quality 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.
• Open-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.
• Wide 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.
• Industrial-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.
