Mamy trzy sposoby ujednostajnienia biegu wielofazowych silników szere¬ gowych: 1. Przez zmiane stosunku ilosc uzwojen statora Ujednostajnienie przez wlaczenie na¬ syconego transformatora szeregowego jest równiez niedogodne. Jezeli przy malej liczbie obrotów ujednostajnienie jest mozebne, to juz przy sredniej liczbie obrotów niestatecznosc ruchu w ten spo- spb usunac sie nie da; silny prad magne- tyzuj acy transformatora szeregowego oddzialywa szkodliwie na cos cp ma¬ szyny.Ujednostajnienie przez dodatkowe wla- ilosc uzwojen rotora 2.

PLThere are three ways to harmonize the run of multiphase series motors: 1. By changing the ratio of the number of stator windings. Unifying by switching on a saturated series transformer is also inconvenient. If, at a low number of revolutions, it is possible to make uniformity possible, then motion instability cannot be eliminated in this way even at an average number of revolutions; the strong magnetizing current of the series transformer has a detrimental effect on the cp of the machine. Unifying by an additional number of rotor windings 2. By switching on a saturated series transformer between the stator and rotor windings (stander and rotor). 3. The use of additional ohmic resistance (cf. German patent No. 284929). Unifying the run by changing the ohmic resistance is inconvenient for the ratio of the number of turns is inconvenient, insofar as this resistance absorbs a part because it causes quite unfavorable changes ; despite the fact that the unification is the bridge of the phases between the current and the tension at each angle of the brushes and between the motor terminals; in addition, a much greater uniformity in this way is the reduction of the efficiency factor, possibly an accident with the conversion. The invention uses combinations of the higher brush angle by less than 90 ° than the 2 and 3 methods mentioned in the short circuit position. he knows completely avoiding their harmful actions. By appropriate selection of the turns, we obtain a single-speed engine having the phases in equilibrium during normal operation, since any other adjustment is unnecessary. The ratio of the number of turns is chosen solely for the purpose of equilibrating the phases in the course of the engine; The homogenization is achieved by switching on a saturated series transformer at engine start-up and by simultaneous application of an additional ohmic resistance. This resistance makes it possible to be uniform at any change in the position of the brushes and at any number of revolutions; the saturated transformer allows the application of as little additional resistance as possible so that the additional losses are very small; while the engine is running, we achieve equilibrium of the phases by appropriately adjusting the number of turns.
