ABSTRACT:
The carrier for linear motor vehicle-borne field magnets includes a aluminium profiled material of a gate shape in section, which is provided with recesses of permanent magnet size in both its legs. Permanent magnets attached to iron cores are inserted into the recesses in such a way that the N and S poles thereof are opposite to each other and alternate in the longitudinal direction of the carrier frame to form a spatial magnetic field by the alternation of the N and S poles between both the legs of the carrier frame, which interacts with the moving magnetic field created by ground-side coils to generate driving power. The carrier further includes support wheels, guide wheels and a vehicle support on which a vehicle is placed.
