To quickly assess the difficulty of the text, read a short excerpt:
E. M. F. Relations for Rotary Converter. Let E be the value of the steady electromotive force between the direct-current brushes of a rotary converter; and let E2, Ez, £4, E^, be the effective values ^^ Digitized by Google ALTERNATING-CURRENT MACHINERY 331 of the alternating electromotive force between adjacent collecting rings of a two-ring, three-ring, four-ring, and six-ring rotary con- verter, respectively. It is desired to find the relationship between these various electromotive forces.
R...elationshiy between E and £2. The maximum value of the alternating electromotive force between the collecting rings of a two-ring converter occurs at the instant when the commutator bars to which the collecting rings are connected are in contact with the direct-current brushes, and this maximum value is, of course, equal to E. Therefore, the effective value £2 of the alternating electromotive force between the slip-rings of a two-ring converter is E equal to Z7^. That is E.= ^ (41) Relationship between E2 and E^, The discussion of the relation- ship between E^ and Ez will be carried out for a very special case, namely, where the armature has 18 conductors; and this special discus- sion will lead to a very simple geo- metrical construction which will easily give the relationship between £2, Ez, E4, and Eb, and will also show the phase relations of the vari- ous electromotive forces of a three- ring, of a four-ring, or of a six-ring converter.
