ABSTRACT:
A moving coil electrical meter mechanism has a substantially rectangular coil and a magnetic structure surrounding first, second and third sides of the coil and defining first, second and third magnetic flux filled air gaps containing magnetic fields so oriented that the forces exerted on the first, second and third sides of the coil are in the same direction. The rectangular coil is mounted to rotate under the influence of the magnetic fields around an axis adjacent to the fourth side of the coil, with the magnetic fields remaining orthogonal to the coil sides during rotation.
