Improvement of Superconducting Linear Motor for Cryogenic Pump

The cryogenic liquids such as liquid nitrogen or liquid hydrogen are used in various fields, and the necessities of these liquids will increase in near future. However, mechanical bearings are not useful in the cryogenic temperature environment. Therefore we decided to develop a linear motor using superconducting coil for cryogenic liquid transportation, and it is easier to transfer the cryogenic liquid. At first we have made a superconducting linear motor and carried out some experiments.
