Hall Brushless High Speed Vacuum Motor Demonstration Model, Interactive STEM Physics Experiment Desktop Display
Features:
.Driven by a precision Hall-effect brushless motor, the device delivers exceptionally smooth and quiet performance while clearly demonstrating the working principles of magnetic suspension and brushless motor technology, even under normal atmospheric conditions.
.Featuring a built-in high-sealing one-way vacuum valve with a dedicated evacuation port, the chamber can be evacuated using a compatible vacuum pump to significantly reduce air resistance. Under reduced-pressure conditions, the motor is capable of reaching rotational speeds of approximately 20,000 to 50,000 RPM, creating an impressive visual demonstration of high-speed rotational physics, aerodynamic drag reduction, and rotor dynamics.
.Compatible with 5V-24V DC power supplies (1A-5A), this demonstration device offers exceptional flexibility for classroom experiments and engineering demonstrations. Operate it using a USB power adapter or power bank for low-speed testing, or connect a laboratory power supply for higher-speed operation. The integrated speed control knob allows smooth adjustment, making it easy to observe how voltage and current influence rotational speed and centrifugal force.
.Constructed with a crystal-clear acrylic tube and support frame, the device provides an unobstructed view of the rotor, magnetic components, and internal structure during operation. The dynamically balanced design enables stable high-speed rotation, allowing users to safely observe the mechanical motion at close range while appreciating the effects of centrifugal force and magnetic suspension. For practice, hold the device by its base during operation.
.More than a striking desktop conversation piece, this device serves as an engaging STEM educational model for demonstrating lectromagnetic induction, brushless motor operation, centrifugal force, and the influence of air resistance on rotating systems. For physics classrooms, engineering laboratories, science museums, makerspaces, or as a collection for students, educators, engineers, and technology enthusiasts.
