摘要：A contour molded galvo-motor coil together with the forming apparatus andthe specific method of manufacture. A low inertia coil is formed which also allows asmaller air gap in the magnetic circuit of the galvo-motor. The associated improvement ingalvo-motor efficiency results from the inverse square relationship between flux densityand length of air gap. The formed coil is shaped as a section of a thin walled circularcylinder and impregnated with a compound during winding which when cured provides arigid unitized coil structure. The low mass resulting from the absence of the conventionalcoil form and the high rigidity afforded by the coil shape and impregnation compoundeliminate torsional deformation during operation and provide a galvo-motor having highefficiency and accuracy.
