摘要： A galvanometer is shown, which includes a cylindrical magnetic rotor polarized into two essentially semi-cylindrical poles on opposite sides of its axis. Two coil portions are disposed on opposite sides of the rotor, separated by a plane of symmetry that is in essential alignment with the poles of the rotor at the center of its range of motion. The legs of each grouping of turns of each coil portion are disposed in a distribution beginning at a point corresponding to the radial surface of the bobbin on which the coil portion is wound, and extending continuously substantially to the plane of symmetry. The distribution may be lower in density at the plane of symmetry than spaced therefrom and may approximate an inverse cosine distribution. A rotor is shown that includes a thin-walled torque-bearing sleeve encircling at least a portion of the magnet and is joined to the output shaft and the magnet. A fastener anchors the bobbin to the shell to prevent relative rotation therebetween. A position transducer is linked to the rotor outside of the space between the bearings to favorably affect the first resonance of the rotor. A winding fixture is shown, and the process of making the coils is described.

摘要： An electric meter particularly characterized by a small number of moving parts and simplified assembly by virtue of fixed cooperating locating surfaces on the elements and sub-assemblies of the meter. A magnetic circuit including a yoke and magnet are constructed to snap into an insulating base in a predetermined position on the base. A coil assembly initially including integral elements for connection of pivot bearings or taut bands is accurately positioned for rotation on the supporting base by inserting the assembly into the base. Cooperating locating surfaces provide for accurate predetermined positioning of the axis of rotation of the coil relative to the magnetic circuit. Additional features of the meter construction reside in a direct gear drive between a zero adjust element and zero adjust knob mounted in a cover for the meter, a unique base, casing, and cover which snap together, a coil support form of unique construction and which includes motion limiting elements which limit the permissible extent of movement of the coil in the event of shock or impact to positions well within the elastic limit of the supports which mount the coil for rotation, a unique mode of terminating the end connections for the coil without the need for stripping insulation, a unique mounting arrangement for the assembled meter, a unique rear mounting scale plate which provides for easily replacing scale plates to meet the needs of the user of the meter, a meter movement of a single size adapted to be used with casings and scales of various sizes whereby the number of different parts required to form meters of different sizes is maintained at a minimum, a unique insulating material base with flexibility to permit expanding the base during assembly of the meter, and sub-assemblies, components, and elements which can be assembled in only one position and orientation to assure proper assembly of the meter.

摘要： An electric meter comprises a cylindrical internal magnet so magnetized as to have N and S poles oriented in a direction such that a straight line connecting both poles intersects with the central axis of the magnet at right angles thereto. First and second circular arc-shaped auxiliary yokes are provided along the magnetized direction of said cylindrical internal magnet, around the outer periphery of the internal magnet, and at prescribed distances from the N and S poles of the magnet, and a movable coil is pivotally mounted in the magnetic field produced between the tip end portions of the first and second auxiliary yokes and the N and S poles of the cylindrical internal magnet.
