ЭЛЕКТРОМАГНИТНОЕ ПОЛЕ В ВОЗДУШНОМ ЗАЗОРЕ СИСТЕМЫ «РОТОР – СТАТОР» РАДИАЛЬНОГО ЭЛЕКТРОМАГНИТНОГО ПОДШИПНИКА

Abstract

A particularly responsible, pronounced assembly unit of the turbine unit is the manufacturer, which has the severity of variable interdependent and mutually influencing boundary conditions that cause the impact on the gas environment, the sharply deformed state of the rotor element base, the oscillatory circuit, the imbalance and the magnetic strength of the electromagnetic support. The constant increase in the rotation speed, the increase in the importance of the structural element of the turbomachine rotor, as well as the reduction in weight and dimensions, bring the increase in the service life of bearing supports to the first place. it can be noted that modern turbine units are consumed in supports, which cause a stable and increased rotor speed in any modes and in any environment. The article considers in a plane-parallel setting numerical simulation of a complexly identified problem of field scattering in the air gap of the "rotor-stator" system of a radial electromagnetic suspension, from the composition of a centrifugal supercharger, with centrifugal rotor levitation, taking into account the radial displacement of the rotor axis during rotation. Based on the results of the calculation, the distribution of the distribution of electromagnetic fields was determined during the weighing of its rotor and during radial displacement and rotation.
