Passive Magnetic Bearings at the Rotary Application

The construction of passive magnetic bearings is shown in the paper. Advantages and disadvantages a passive magnetic bearing with magnets, superconductors and electro-dynamic bearing are presented by Authors. They discus influence such parameters as load, speed of rotor, temperature and cost design and exploitation of bearing. Here are presented construction of the passive magnetic suspension designed for jet engines and linear bearing for UAV’s launchers.

Experimental measurements of levitation force generated by high-temperature superconductors in magnetic field

This paper describes the measuring procedure of the levitation force, as a function of levitation gap. Levitation force is a consequence of the Meissner effect occurring between superconductor and the magnetic field. Those experiments are part of studies on magnetic Unmanned Air Vehicles Catapult dynamics. Described experiments used height quality testing machine, box with four height-temperature superconductors YBCO and part of magnetic catapult rail system made of neodymium magnets.

Numerical and Experimental Testing of Bearingless Induction Motor

The bearingless systems are a key technology in many power mechatronic applications. The topic of the paper reports the original, very relevant and very timely research. The methods of numerical and experimental testing of the bearingless induction motor, presented in the paper revised, are convergent with the directions of up-to-date research in this domain.
