NUMERICAL FIELD ESTIMATION OF TURBOGENERATOR STATOR WINDING SHORTENING EFFICIENCY
On the basis of numerical calculations of rotating magnetic field, a turbogenerator is evaluated for cases of a shortened stator winding and a diametric one. The parameters compared are the shape and harmonic composition...
SHIELDING OF A UNIFORM ALTERNATING MAGNETIC FIELD USING A CIRCULAR PASSIVE LOOP
The magnetic and electromagnetic shields are used to reduce the magnetic field in local spaces. Usually these shields are implemented in the form of a box or a cylinder. At the same time the magnetic field reduction in l...
THE THYRISTOR CONVERTER INFLUENCE ON THE PULSATIONS OF THE ELECTROMAGNETIC TORQUE OF THE INDUCTION MOTOR AT PARAMETRICAL CONTROL
Purpose. The purpose of the work is to identify the parameters influence of the electric motor, the power circuits elements of the converters, built on resistor-thyristor modules, the static torque and the moment of iner...
PHYSICAL MEANING OF THE «REACTIVE POWER» CONCEPT APPLIED TO THREE-PHASE ENERGY SUPPLY SYSTEMS WITH NON-LINEAR LOAD
Purpose. The contradictions in the use of the term «reactive power» require justification by clarifying its physical meaning. The aim of the paper is to reveal the physical meaning of the term «reactive power» applied to...
