摘要
常导电磁吸力悬浮系统悬浮气隙小、悬浮功率大,电动斥力悬浮系统不能实现静止悬浮、磁场污染大。由于受电流变化率限制,单独采用高温超导线圈构成的电磁吸力悬浮系统不能实现稳定悬浮。经分析比较,提出了一种用高温超导线圈和常导线圈构成的混合式电磁吸力型悬浮系统方案。采用这种混合式悬浮方案可增大悬浮气隙、实现稳态"零"功率悬浮、减轻车体重量、降低制冷费用、且无磁场污染。
The normal electromagnetic suspension systems have little air gap and large power, the electrodynamic suspension systems can't realize static suspension and have magnetic pollution, while the stable suspension can't be realized only with high temperature superconductor coil because of its limited current rate. This paper presents a new suspension system with hybrid electromagnets made of high temperature superconductor and normal conductor coil. When this system is employed in an attractive electromagnetic vehicle, it results in a large air gap and nearly zero power when the system is stable, having a lighter vehicle weight, a much cheaper refrigeration cost and a much lower magnetic fields in the cabin and also at external of the vehicle.
