    W artykule opisano wp艂yw podwojenia liczby faz w silniku synchronicznym z magnesami trwa艂ymi na wybrane parametry elektryczne i mechaniczne silnika, na przyk艂adzie silnika nap臋du eKIT przeznaczonego dla elektrycznie nap臋dzanych pojazd贸w dostawczych o dopuszczalnej masie ca艂kowitej do 3.5 t i mobilnych maszyn specjalnych. Szczeg贸艂owo przedstawiono konstrukcj臋 uzwojenia w wariancie 3-fazowym i spos贸b przekszta艂cenia 3-fazowego uzwojenia symetrycznego w dwugwiazdowe asymetryczne uzwojenie 6-fazowe. Nast臋pnie przedstawiono wyniki oblicze艅 elektromagnetycznych i por贸wnano wybrane parametry elektryczne i mechaniczne silnik贸w w wariantach z 3- i 6-fazowym uzwojeniem twornika.The article describes the effect of doubling the number of phases in a permanent magnet synchronous motor on selected electrical and mechanical parameters of the motor, based on the example of an eKIT drive motor intended for electrically driven delivery vehicles with a total weight of up to 3.5 t and special mobile machines. The construction of the winding in the 3-phase variant and the method of transforming a 3-phase symmetrical winding into a double-star asymmetric 6-phase winding are presented in detail. Then, the results of electromagnetic calculations are presented and selected electrical and mechanical parameters of motors in variants with 3- and 6- phase armature windings are compared

    W artykule opisano modernizacj臋 obwodu elektromagnetycznego (wzbudnika) separatora zaprojektowanego oko艂o 50 lat temu. Separator jest stosowany w przemy艣le g贸rniczym i s艂u偶y do oddzielania drobnych cz膮stek magnetycznych od niemagnetycznych. G艂贸wnym elementem roboczym separatora jest wzbudnik elektromagnetyczny zasilany 3-fazowym pr膮dem przemiennym, kt贸ry wytwarza w臋druj膮ce pole magnetyczne. Pole ci膮gnie za sob膮 cz膮steczki magnetyczne, kt贸re gromadz膮 si臋 na kraw臋dzi separatora, sk膮d s膮 usuwane. W ten spos贸b cz膮stki magnetyczne s膮 oddzielane. Do takiego zadania zaproponowano zmodernizowan膮 konstrukcj臋 wzbudnika separatora, kt贸ra mo偶e zast膮pi膰 stary separator, przy znacznie mniejszych wymiarach gabarytowych i masie. Now膮 konstrukcj臋 separatora opracowano na bazie silnik贸w liniowych projektowanych wcze艣niej w instytucie 艁ukasiewicz - KOMEL.The article describes the modernization of an electromagnetic circuit (exciter) of a separator designed about 50 years ago. This separator is used in the mining industry and is designed to separate fine magnetic particles (powder) from non-magnetic ones. The main working element of the separator is an electromagnetic exciter powered by 3-phase alternating current, which generates a running magnetic field. The field pulls magnetic particles that accumulate at the edge of the separator, from where they are removed. In this way, the magnetic particles are separated. For such a task, a modernized design of the separator exciter has been proposed, which can replace the old separator, with much smaller dimensions and weight

    Semiotics of Art

    "A vital force in European linguistics and literary scholarship in the 1930s, the Prague School opened up the rich field of semiotics and art. The study of art as the creative use of the sign became one of its principal areas of critical examination, and in this collection of 21 essays this concept of semiotics is brought to bear on a wide range of the arts, including theater, film, poetry, folk art, and painting." -- p.

    Intersubjective Traps over Tricks on the Kazakhstani Puppet Stage: Animation as Dicentization

    No full text
    This article introduces puppet animation as a process of dicentization, in which the puppet's resemblance to a living creature is treated as if it resulted from the object being alive. This act requires recognition that the puppet is only an object, accompanied by a momentary forgetting. At a state-funded theater in Kazakhstan, animation is achieved through a complex participant framework. Any component can jeopardize successful animation, yet this configuration enables a range of possibilities for how animation can unfold. A director's shifting of animation techniques transformed social relations and enabled artists to play with new possibilities of puppetry. Coordinating animation requires鈥攁nd thus assigns鈥攙alues to those who participate. Understanding animation as dicentization highlights the endeavor as one that generates signs across the proscenium
