      <title>NORMAL FORCE VARIATION IN SINGLE-SIDED LINEAR INDUCTION MACHINES</title>
      <link>https://trid.trb.org/View/60282</link>
      <description><![CDATA[A basic 1-D model having a single harmonic current sheet supported on infinitely permeable iron, an air-gap, a conducting layer and a backing region of air or iron is discussed.  By making certain simplifying assumptions, two circle diagrams can be derived, one for the model with backing iron, the other without.  It is shown how the idea might be extended to include normal force and machines having air-backed rotors.  Simple formulae are derived for certain factors such as complex power/newton of normal force.]]></description>

      <title>ASSESSMENT OF LINEAR SUPERCONDUCTING MOTORS FOR MAGLEV</title>
      <link>https://trid.trb.org/View/60283</link>
      <description><![CDATA[Linear synchronous machines (LSM) and linear commutator machines (LCM) are considered and compared.  Overall costs of linear machines are relatively insensitive to pole pitch, thus allowing this parameter to be chosen on other grounds. The overall costs of an LCM appear to be comparable with those of the LSM, provided that the simple machine being investigated is technically acceptable.]]></description>
