Outline of lecture
Magnetic Levitation and Magnetic Suspension
At the era of the 21 century, magnetic levitation and suspension have been introduced into some practical applications. There are maglevs such as the JR Yamanashi Maglev, the Linimo train in Nagoya, and the Shanghai Maglev. On the other hand, bearingless motor water pumps for pure water, magnetic bearings for turbo molecular pumps are used in semiconductor processes. In this lecture, we will study about super conductor magnetic levitation, Maglev train systems, magnetic bearings, and bearingless motors.
