FORCES ON MAGNETICALLY LEVITATED VEHICLES ABOVE FLAT GUIDEWAYS -- A MODELLING TECHNIQUE
Split guideway using a completely flat track, with a gap down the centre that can be used to accommodate the winding of a linear synchronous motor is described. With this system, there is a need to relate the magnetic forces to the guideway dimensions, such as the track width and the centre gap width. A suitable method for calculating the forces, and the results obtained on a .44 m diameter rotating disc model are presented. Ferrite permanent magnets are used instead of coils, and the parameters that are varied include height above the sheet, pole pitch, polarity of adjacent poles, field strength, and position with respect to the disc's edge.
