Abstract
20,803. British Thomson-Houston Co., [Thomson, E.]. Oct. 17. Energy meters for alternating currents. An induction motor meter consists of stationary main current and pressure coils C, B, producing separate magnetic fields in which are two armatures A<1>, A<2>, carried by or geared to one spindle S so that they rotate together. The armatures are interconnected, each consisting of a core surrounded by two or more coils, and each coil on one armature being permanently connected in a closed circuit with a coil on the other. If the field coils B, C are all parallel, as shown, the coils on one armature are all displaced about the spindle from the connected coils on the other armature, the displacement being 45‹ if each armature carries two coils, or 60‹ for three. Otherwise each pair of interconnected coils may be in one plane, and one set of field coils placed at a suitable angle to the other. An inductive coil I may be connected in series with the pressure coil B, between the mains. A starting coil K, adjacent to the main current coil C, is connected between the mains, to compensate for friction. The spindle is geared to a counter R, and provided with a magnetic or other retarding- device M.
