The report is a preliminary evaluation of the technical feasibility of using iron-cored, synchronously operating motors to propel ground transportation vehicles in the high cruise speed range. A second consideration is the possibility that the motor might also provide strong attractive and lateral forces. Three motor types, all realizable with passive track rails are investigated: (a) claw-pole synchronous motor, (b) homopolar inductor motor, and (c) heteropolar inductor motor. A rail clearance of 1.5 cm is specified. However, the effect of variations in this and other design parameters is also analyzed. All three types considered compare favorably with an equivalent single-sided induction motor, insofar as weight, efficiency, and power factor are concerned. The calculations are supported by analog simulation experiments.
