Linear Induction Motor Experiments in Comparison with Mesh/Matrix Analysis

A four-pole, 0.9-meter-long linear induction motor was tested in a rotating-disc facility at speeds up to 300 MPH (483 Km/Hr). The results were compared with predictions from a mesh/ matrix analysis method. The magnetic field and secondary (disc) current were method. The magnetic fiel and secondary( dsc) current were predicted to rise from low values at the entrance to peaks near the exit and to decay over a span of one to several pole pitches beyond the exit. Magnetic field measurements verified internal details predicted. Measured thrusts agreed with the mesh/matrix analysis within 10 percent. The results are considered to furnish verification of the mesh/matrix analysis method.
