Abstract
18,470. Johnson, W. H., and Billington, A. M. Aug. 4. Induction motor meters; brakes.- The pole-faces of the driving-magnet have a total width, measured in the direction of motion of the disk or cylinder, less than their length in the radial or axial direction. Preferably, the width is very much less than the length, and the pole may consist of a single sheet. In the meter shown, the magnet is made up of groups of stampings of the form shown in Fig. 5; the stampings may be slit at h to facilitate the winding of the pressure coils j. The groups are separated by, and arranged between, shorter rectangular plates g of non- magnetic material. Current coils m are wound on each of the groups, the pressure coils j surrounding all the groups. A brake magnet of the kind described in Specification 16,332/09 may have its energizing-windings connected in the circuit of the pressure coils j.
