Purpose. To find the analytical expressions of determining the optimum geometric dimensions by criteria of the losses minimum of axial field squirrel-cage induction motors and to compare traditional and axial field motors. Methodology. We have applied the method of the relative indications of the technical level with relative controlled variables. We have used the approximation of the experimental dependence of the distribution of the induction in the air gap and the integral averaging of the magnetic flux. Results. We have developed the mathematical model for determining the optimum geometric dimensions by criteria of the losses minimum of the active part of axial field squirrel-cage induction motors taking into account the radial distribution of the induction in the air gap and teeth. We have considered the comparative analysis of the indications of active power losses of traditional and axial designs of electromagnetic equivalent motors. Originality. For the first time we have created the mathematical model of the active power losses of the active part of axial field squirrel-cage induction motors with the uneven distribution of the magnetic flux in the core and investigated the effect of the geometric relationships on the energy efficiency of axial field motors. Practical value. Based on the superior parametric compatibility and the high energy efficiency of axial motors the expediency of replacing traditional induction motors to axial field induction motors has been proved in the special drives, which operates in continuous duty. Also obtained by simulation optimal geometric relationships of the magnetic circuit can be used in the manufacture and design of axial motors by criteria of the losses minimum.ΠΠ° ΠΎΡΠ½ΠΎΠ²Π΅ ΠΌΠ΅ΡΠΎΠ΄Π° ΠΏΠΎΠΊΠ°Π·Π°ΡΠ΅Π»Π΅ΠΉ ΡΠ΅Ρ

Physics Opportunities at ELFE
I review some central physics opportunities at the 15 ... 30 GeV continuous
beam electron accelerator ELFE, proposed to be built in conjunction with the
DESY linear collider. Our present detailed knowledge of single parton
distributions in hadrons and nuclei needs to be supplemented by measurements of
compact valence quark configurations, accessible through hard exclusive
scattering, and of compact multiparton subsystems which contribute to
semi-inclusive processes. Cumulative (x>1, x_F>1) processes in nuclei measure
short-range correlations between partons belonging to different nucleons in the
same nucleus. The same configurations may give rise to subthreshold production
of light hadrons and charm.Comment: 16 pages, 3 figures included using epsf. (Misprint in Eq. (8)
corrected in revised version.
Analysis of hadron production in nucleus-nucleus interactions up to and out of kinematical limit of free NN-collisions in the frame of FRITIOF model
In the framework of the modified FRITIOF model, the inclusive spectra of the
cumulative -, -mesons and protons produced in the
nucleus-nucleus interactions at 4.5 GeV/c/nucleon and 4.2 GeV/c/nucleon are
calculated. It is shown that the model reproduces qualitatively, and in some
cases quantitatively the main experimental regularities of -mesons
production, and "soft" part of the proton spectra. According to the model the
production of the cumulative particles is connected with the mechanism of the
"soft" nucleon-nucleon interaction.Comment: 12 pages, 11 figure
Light Front Formalism for Composite Systems and Some of Its Applications in Particle and Relativistic Nuclear Physics
Light front formalism for composite systems is presented. Derivation of
equations for bound state and scattering problems are given. Methods of
constructing of elastic form factors and scattering amplitudes of composite
particles are reviewed. Elastic form factors in the impulse approximation are
calculated. Scattering amplitudes for relativistic bound states are
constructed. Some model cases for transition amplitudes are considered. Deep
inelastic form factors (structure functions) are expressed through light front
wave functions. It is shown that taking into account of transverse motion of
partons leads to the violation of Bjorken scaling and structure functions
become square of transverse momentum dependent. Possible explanation of the
EMC-effect is given. Problem of light front relativization of wave functions of
lightest nuclei is considered. Scaling properties of deuteron, and
light front wave functions are checked in a rather wide energy range.Comment: Review paper, Submitted to Phys. Rep., 89 pages, 23 figure
COMPARATIVE ANALYSIS OF ACTIVE POWER LOSSES OF INDUCTION MOTORS WITH CYLINDRICAL AND AXIAL AIR GAPS
Purpose. To find the analytical expressions of determining the optimum geometric dimensions by criteria of the losses minimum of axial field squirrel-cage induction motors and to compare traditional and axial field motors. Methodology. We have applied the method of the relative indications of the technical level with relative controlled variables. We have used the approximation of the experimental dependence of the distribution of the induction in the air gap and the integral averaging of the magnetic flux. Results. We have developed the mathematical model for determining the optimum geometric dimensions by criteria of the losses minimum of the active part of axial field squirrel-cage induction motors taking into account the radial distribution of the induction in the air gap and teeth. We have considered the comparative analysis of the indications of active power losses of traditional and axial designs of electromagnetic equivalent motors. Originality. For the first time we have created the mathematical model of the active power losses of the active part of axial field squirrel-cage induction motors with the uneven distribution of the magnetic flux in the core and investigated the effect of the geometric relationships on the energy efficiency of axial field motors. Practical value. Based on the superior parametric compatibility and the high energy efficiency of axial motors the expediency of replacing traditional induction motors to axial field induction motors has been proved in the special drives, which operates in continuous duty. Also obtained by simulation optimal geometric relationships of the magnetic circuit can be used in the manufacture and design of axial motors by criteria of the losses minimum
COMPARATIVE ANALYSIS OF WEIGHT AND COST INDICATIONS OF INDUCTION MOTORS WITH CYLINDRICAL AND AXIAL AIR GAPS
Purpose. To find the analytical expressions of determining the optimum geometric dimensions by criteria of the weight minimum and the cost minimum of axial field squirrel-cage induction motors and to compare traditional and axial field motors. Methodology. We have applied the adapted method of the relative indications of the technical level with relative controlled variables. We have used the approximation of the experimental dependence of the distribution of the induction in the air gap and the integral averaging of the electromagnetic characteristics. Results. We have developed the mathematical model for determining the optimum geometric dimensions by criteria of the weight minimum and the cost minimum of the active part of axial field squirrel-cage induction motors taking into account the radial distribution of the induction in the air gap and teeth. We have considered the comparative analysis of the indications of the weight and the cost of traditional and axial designs of electromagnetic equivalent motors. Originality. For the first time we have created the relative units mathematical model of the weight and the cost of the active part of axial field squirrel-cage induction motors with the uneven distribution of the magnetic flux in the core and investigated the effect of the geometric relationships on the materials consumption and cost of axial field motors. Practical value. Based on the superior parametric compatibility and the high material savings of axial motors the expediency of replacing traditional induction motors to axial field induction motors has been proved in the special transport drives. Also obtained by simulation optimal geometric relationships of the magnetic circuit can be used in the manufacture and design of axial motors by criteria of the weight minimum and the cost minimum

ΡΡΠ°ΡΠΎΡΠ° Ρ ΡΠΎΡΠΎΡΠ°.On the basis of a method of relative technical level indices with relative geometric controlled variables, analytical expressions are derived to determine the optimum geometric dimensions of the squirrel-cage induction motor active part under criteria of the weight and the cost minimums. Comparative analysis of the mentioned indices for the conventional and the inverted stator and rotor designs is performed
