Title: Improvements in or relating to rotary converters
IPC: H02K47/02
Filed: 1922-03-13
Abstract: 178,090. Forges et Ateliers de Constructions Electriques de Jeumont, (Assignees of Ateliers de Constructions Electriques du Nord et de l'Est). April 5, 1921, [Convention date]. Rotary converters. - A single machine for converting alternating into continuous currents and having the characteristics of a cascade motorconverter has a rotor R driven by a synchronous motor r in the opposite direction to that of the rotating field of the stator S, the number of continuous-current brush rows on the commutator being different from the number of alternating-current poles in the rotor. The number of commutator segments is n pc/pa, where n is the number of winding sections in the rotor, pc the number of continuous-current brush rows or poles and pa the number of alternating-current poles, and each section of the rotor winding is connected to pc/pa segments symmetrically spaced around the commutator. The motor r, which is fed from the same source as the stator S, has 2 (pc-pa) poles and has a minimum power output such that its ratio to that of the total power of the converter is equal to that of pa to pc. The converter may be compounded by compounding the exciter E of the rotor r with the continuous current from the converter. The machine may be started by an auxiliary synchronous motor connected directly to the network by means of an inductance. In addition to the main winding, the rotor R carries a short-circuited compensating winding consisting of two sets of coils A<1>, A<2> of full pitch and one-third pitch respectively each turn of the winding A<1> being connected in parallel with two of the winding A<2>. The Specification as open to inspection under Sect. 91 (3) (a) describes also a two-rotor cascade converter in which the connections between the rotors are such that the field in the secondary continuous-current rotor revolves in the same direction as the revolving field in the primary stator and rotor; also the use of a squirrel cage winding on the " inductor " of the machine which causes the group to revolve in an opposite direction to the field. This subject-matter does not appear in the Specification as accepted.
