Abstract
INVESTIGATION OF THE INFLUENCE OF THE CURRENT FREQUENCY ON THE RESISTANCE OF THE INDUCTION RHEOSTAT BY MEANS OF THE SOLUTION OF FIELD EQUATIONS IN THE 3D FORMULATION. Syanov O.M., Kosuhina O.S., Polyakov R.M. Abstract The purpose of the work is to create a model of "classical" design of IP and conducting numerical studies, due to the results one can corroborate or knock the bottom out of the possibility of reducing the copper coil by increasing the frequency of supply voltage. As a result of the simulation and calculations, it may be concluded that increasing the frequency of power supply in the IP leads to the possibility of reducing the number of turns in the coil and reducing its weight almost twice. As it can be seen from the simulation results, this is exactly resistive indicators, further increase of frequency allows to reduce the number of turns of the coil in several times. Thus, according to the mathematical IP models realized in the nonlinear software environment, improvement of the design of the IP in the direction of reduction of mass-overall measures is technically practicable and economically sound. Further research in this direction can lead to a decrease in the thickness of the plates and the outer and inner diameter of the IR ring. References [1] Syanov O.M.
