49,165 ABSTRACT OF THE DISCLOSURE An induction meter including a voltage and a current magnetic sections each producing magnetic flux for driving a rotatable disk at a rate responsive to an AC electric energy quantity to be measured is disclosed. The induction meter has an improved voltage magnetic section comprised of a substantially E-shaped laminated magnetic core having a center leg terminating at a main pole face and two adjacent legs terminating at coplanar auxiliary pole faces on opposite sides of the main pole face. The first and last laminae of the magnetic core define a first and second side, respectively, of the core. A voltage coil is wound about the center leg. A nonmagnetic multi- function support and spacer bracket extends from one of the adjacent legs to the other adjacent leg. The bracket has three perpendicular extensions which give the bracket a substantially E-shaped configuration. Each of the perpendicular extensions corresponds to one of the legs of the magnetic core. The bracket is located adjacent to the first side of the magnetic core and has one edge substan- tially coplanar with the auxiliary pole faces. A perpen- dicular extension corresponding to the center leg provides support for the voltage coil. A light load adjuster bracket provides an adjustable shunt path for magnetic flux between the main pole face and the auxiliary pole faces. The light load adjuster bracket is located in magnetic proximity to the first side of the magnetic core and is separated therefrom by the nonmagnetic bracket. A 49,165 power factor bracket extends from the second side of the magnetic core. A flux return tongue is carried by the power factor bracket and is located opposite the main pole face while maintaining a spaced relationship therewith. The electroconductive disk rotates within this predeter- mined space.
