HARMONIC ANALYSIS OF MAGNETOMOTIVE FORCE IN THE AIR GAP OF SIX-PHASE ASYNCHRONOUS MACHINES
Get PDFAsynchronous motors with six and more phases (usually n-three-phase) are increasingly accepted in electric drive systems of road transport, marine and even aeronautical transport. Multiphase machines are credited with multiple advantages such as: less torque ripple, better power distribution per phase, higher efficiency and fault tolerance capability compared to traditional three-phase machines. There are many publications, but few of them are dedicated to the in-depth study of the multiphase motor (m>3) and especially of the magnetic field in its air gap. The purpose of the present paper: the development of the mathematical model of the magnetomotive force in the air gap of the six-phase asynchronous machines, which determines the fundamental properties of the machine, the structure of the magnetic field and the torque developed, the efficiency, the error tolerance. The research is based on analytical studies and the results of suitable experimental measurements. The paper presents the mathematical model for the harmonic analysis of the magnetomotive force in the air gap of six-phase machines with possible variants of windings on the stator. Based on this study, it was demonstrated that only n-three-phase machines with asymmetrically arranged stator windings have the ability to attenuate higher harmonics with a major negative effect on the developed torque, the applicability and efficiency of traditional tools for reducing higher harmonics in the case of six-phase machines was confirmed. The results of measurements carried out on samples of six-phase machines confirm the findings and conclusions formulated in the paper

This study highlights the vital role of contemporary jewelry in preserving and transmitting Romanian Cultural Values in Bessarabia to future generations and in creating deep connections between artists, designers and the local community. It also highlights the importance of national identity in the development of contemporary jewelry, which can contribute to the promotion of Romanian traditions and crafts in the contemporary global context
THE LINGUISTIC RECONSTRUCTION OF POST-COLONIAL SOUTH AFRICA AND LESOTHO: ENGLISH DOMINANCE DILEMMA
Get PDFLanguage was one of the tools used by colonialists in destroying the heritage of African nations. Yet, there is limited research on how African nations have linguistically faired post their independence. The purpose of this paper is to assess the endeavors of two neighboring African governments, South Africa and Lesotho, in the post-colonial era to linguistically reconstruct their nations. Qualitative data were collected through a comparative analysis of these two countries’ constitutions, with a focus on language rights and language in education. The data analyses were conducted using the language planning theory to evaluate how available policies enhance the position of previously marginalized African languages. The results revealed that whilst South Africa has a linguistic diversity challenge and Lesotho a language homogeneity advantage, they both still retain a colonial language, English. The international status of English has resulted in it retaining its colonial dominance as a lingua franca, a language of economy, politics and education. There is still more work that needs to be done by African nations to redress the past oppressive policies that devalued their languages. Education should be given priority as a vehicle to revitalize and intellectualize African languages and liberating Africa from its dependency on colonial languages, whilst also promoting multilingualism
THE FEATURES OF AESTHETIC EDUCATION FOR THE DEVELOPMENT OF VISUAL LANGUAGE OF ARCHITECTURE STUDENTS
Get PDFThis work emphasizes some theoretical and practical provisions of aesthetic education, which have an important role in the development of visual language of architecture students. The principle of integrating scientific knowledge and creative skills ensures the success of the architecture student, valuing language as a tool used in free expression. One of the solutions refers to the analysis of the architectural context and project development based on visual language skills, and brainstorming, an idea-generating activity, can be taken as a method. Another solution would be to encourage students to take responsibility for the transmission of visual language from the perspective of aesthetic values. Taking on the role of a future architect by developing analytical skills and conveying aesthetic values, the student gains experience in modelling space and effectively conveying visual images of architectural edifices
THE INFLUENCE OF CULTURAL HERITAGE IN THE FORMATION OF SOCIOCULTURAL VALUES
Get PDFThe work presents an analysis of cultural concepts, heritage and values, their significance is also mentioned in the process of training young people in university institutions. The paper mentions the functions and aspects that emphasize the role of sociocultural values in the development of the personality of young people. Culture has a great influence on how we are aware of the community we are part of and the value system formed during development. Sociocultural values through cultural and social affiliation, reflect references such as the history and qualities of artistic heritage or association with remarkable personalities. Within the university education process, the emphasis is on contributing to their knowledge, protection and promotion. Therefore, the university education process has a considerable impact on the valorization of cultural heritage and the formation of sociocultural values of young people, which will serve as a means of adaptation and integration in the current period
