] N S is an electro-magnet, _a a_ the armature, wound as a Gramme ring, and fixed to a frame with four arms, which can turn freely upon a pivotmidway between the poles. The cross arms of the frame are attached at 1, 2, 3, 4, Fig. 2. Between the magnets and the armature is placed thedistributor, _d d_, where it occupies an annular space open above andbelow. Both the magnets and the armature are coated on the sides facingthe distributor with mica or some other non-conductor of heat andelectricity.... The distributor is attached to and supported by the crossarms, so that it turns with the armature.
The distributor is composed of a ribbon of iron or nickel, bent into acontinuous zigzag. This form has the advantage of presenting, in thecool part of the distributor, an almost direct road for the lines offorce between the poles and the armature, thus diminishing the magneticresistance as far as possible. At the same time the Foucault currentsare minimized. To the same end it is useful to slit the ribbon, as inFig.
