Experimental evaluation of a high speed double sided linear induction motor

Design details and performance testing of a high speed linear induction motor and test facility are described. The motor is double sided and of sector shape with radial slots. It has 4 poles, is 3 feet in length and is loaded by reaction with an 80 inch diameter rotating disc facility. Performance testing including efficiency, power factor, thrust, and normal force and moment are reported for operation over a speed range up to 300 MPH. A breakdown of losses, including end effects, and measurements of air gap flux density over the length of the motor are also reported. A description of instrumentation, the data Acquisition system and the load loop is given. The results are expected to be used to increase the understanding of LIM behavior and design and to provide a data base for the verification of new designs and new theoretical models.
