This project investigated the possibility of using superconducting bearings in large (3 - 100 MW) electric drives. Superconducting bearings are used to levitate the rotors inside electric drives via the Meiissner effect, whereby superconductors tend to repel magnetic flux. The Finite Element Method was used to model superconducting bearings and optimize their dimensions. Computer simulations were written to simulate the superconducting state as well as perform the optimization. Not only the effect of changing the dimensions of the bearings was explored, but also how effects specific to type II superconductors -such as the partial penetration of magnetic flux- could be used to improve bearing design were considered. Ultimately, a superconducting magnetic bearing with a carrying force of 3210 N was improved to obtain a carrying force of 5200 N.
