An investigation of two HSGT magnetic suspension systems (attraction)

Two alternate attraction magnetic suspension systems are discussed on a magnetic performance basis, as well as on their lift-to-weight ( ) capabilities. On an equal current basis, the lower reluctance, flat track configuration has higher lift force and better than the U-shaped track configuration with its larger leakage flux. With equal magnetization (unequal currents) and low guidance forces ( ), the U-shaped track has a higher ratio, but both attraction systems suffer from low when all elements of the suspension system are considered.
