Abstract: 30,628. British Thomson-Houston Co., [Thomson, E., and Pratt, W. H.]. Dec. 28. Energy meters.- Induction motor meters for alternating currents, available for non- inductive or inductive loads, and adjustable for any ordinary frequency. Fig. 5 shows a horizontal section of the motor portion. A hollow cylindrical arma ture A, carried by a vertical spindle, rotates in the spaces between a stationary magnet Q and a frame K, both of laminated iron. The magnet Q is wound with fine wire coils, connected in series with a separate inductance coil, between the mains. The frame K has two polar extensions 0, O<1> near the magnet Q, and two others N, N' which are magnetized oppositely by coils C, C' carrying the main current. The frame K also carries coils a, which are connected in a closed series, and retard the magnetization of the shunt magnet Q to exactly 90‹ from the phase of the main electromotive force. In the construction of the meter, the iron parts K, Q are screwed to projections on a bracket attached to a metal backplate. The vertical spindle is carried between jewelled bearings on screws on this and an upper bracket, and gears with a counter on the upper bracket. It carries a conducting-disc within two permanent brake-magnets supported by the upper bracket. This also carries the inductance coil. Four terminal plates are provided on a board attached to the back - plate below the lower bracket. Resistances, inductive. The inductance used in the meter is a coil wound on the middle of a core P, Fig. 4. This is placed within a frame H, which forms magnetic circuits closed except for small air-gaps t. The core and frame are screwed to a non-magnetic plate. Small misplacement of the core in the frame does not affect the total air-gap. The coil is connected at several points with the studs of a switch, by which portions of it may be cut out of the potential circuit of the meter. This enables the meter to be used with currents of various frequencies, while the air-gaps t render the readings of the meter correct throughout its range.
