      <title>SPATIAL FOURIER TECHNIQUES AND END EFFECTS IN THE SINGLE-SIDED LINEAR INDUCTION MOTOR</title>
      <link>https://trid.trb.org/View/187327</link>
      <description><![CDATA[The spatial Fourier integral technique is used to calculate the secondary field in the airgap of a finite length SSLIM. The calculations are based on the results obtained for the infinite-length counterpart of the machine. The method proposed by Schieber is used in order to avoid the computation of inverse Fourier transforms. The calculated quantities yield the output relations for forces, power and airgap efficiency; end effects are incorporated through this technique.]]></description>

      <title>DESIGN STUDIES FOR SINGLE-SIDED LINEAR ELECTRIC MOTORS: HOMOPOLAR SYNCHRONOUS AND INDUCTION</title>
      <link>https://trid.trb.org/View/160429</link>
      <description><![CDATA[Designs are made for longitudinal-flux, single-sided linear induction machines (SLIMs) and transverse-dc-flux homopolar linear synchronous machines (HLSMs).  All machines have passive reaction rails.  The machines are designed to provide tractive effort for conventional rail vehicles requiring output power from 200 to 3735 kW and top speeds ranging from 112 to 400 km/hr.  Magnetic levitation is not a design consideration for these vehicles.  All designs are optimized to achieve minimum track weight and are made according to specified magnetic and thermal criteria.]]></description>

      <title>ASYNCHRONOUS AND SYNCHRONOUS LINEAR MOTORS OF SHORT PRIMARY CONSTRUCTION</title>
      <link>https://trid.trb.org/View/153463</link>
      <description><![CDATA[Recent research in ground transportation has aimed at the construction of vehicles with high speeds (400 km/h to 500 km/h) where the thrust is produced by linear motors, and suspension is realized by magnetic systems.  Because of economic considerations many of these projects had quickly been finished or given up, so that results comparing different systems are not yet available.  The present paper gives the results of one of these comparative studies.]]></description>

      <title>DC BRAKING CHARACTERISTICS OF DOUBLE-SIDED LINEAR INDUCTION MOTORS</title>
      <link>https://trid.trb.org/View/145728</link>
      <description><![CDATA[An analysis of dc braking performance of linear induction motors is presented.  Specific phenomena such as longitudinal end-effects and transverse edge-effects are taken into account.  Computed results are compared with test results available for the dc braking characteristics of the existing largest double-sided linear induction motor.]]></description>

      <title>ANALYSIS OF A MECHANICAL METHOD FOR DYNAMIC STABILIZATION OF TUNED CIRCUIT LEVITATORS</title>
      <link>https://trid.trb.org/View/60305</link>
      <description><![CDATA[The paper describes recent developments in the field of tuned circuit levitators.  Static stability is attained in such levitators by employing a suspension electromagnet which is the inductive part of a resonant circuit.  However, it is already well known that a tuned circuit electromagnet on its own is usually not sufficient to maintain levitation for long periods of time, and the suspended object tends to be dynamically unstable.  The dynamic instability is prevented in the work described here by adding an auxiliary electromagnet in parallel with the main suspension electromagnet.  Mechanically damping vibrations of an aluminum plate in the field of the auxiliary electromagnet serves to prevent the system as a whole from performing coupled oscillations.  This new process of stabilization has been briefly described in a recent paper, and it is now investigated both experimentally and analytically.  The approximation of slowly varying quantities is used for the analysis, and the dynamic behavior of the complicated nonlinear electromechanical system is successfully interpreted.]]></description>
