Levitating rotor released at 6100 rpm imaged with a stroboscopic technique

<p dir="ltr">Superconducting levitation bearing spin-down experiment showing a magnetic rotor being released from a drive motor at 6100 rpm above a high-temperature superconductor. Footage on the left is captured by a webcam. Footage on the right is captured using a stroboscopic imaging system which makes the rotor appear frozen about the axis of rotation. This eliminates motion blur allowing changes in rotor position and orientation to be determined by machine vision tracking of the inverted T-shaped markers.</p>
