| 摘要 |
<p>The invention relates to first and second magnetic units (34, 35) having a plurality of groups of permanent magnets (51) arranged in side by side relationship, with each plurality being separated from an adjacent plurality by a magnetically permeable member (52) to focus the lines of flux. These groups are separated from their supports by a non-magnetic member (58). The second plurality is spaced adjacent the first plurality with oppositely facing poles, so that they attract each other to levitate a vehicle (10). A hydraulic unit (45) is used to adjust the air gap between respective pairs of the units (34, 35). The units (34, 35) can also be used as the main components of a linear motor (19) so as to propel the vehicle (10).</p> |
