László Kazup, Angéla Váradiné Szarka

Abstract

This paper introduces research of magnetic fields with special attention to distortion of induction in the air-gap of a linear magnetic brake and effects of this distortion. This work is part of a research project aiming to find the most efficient and accurate method for development of linear magnetic brake for dynamic tests in industrial applications. In such applications characteristics of the braking force should be precisely defined and generated therefore control of this system requires highly reliable and accurate function definition between the braking force and the controlling current. In this part of the research dependency between the force and current is analysed, new measurement and analysing system is developed for special requirements, simulation results and real test results are presented in the paper. Results of the diagnostics are used to define braking effects and for development of compensation methods used in dynamic systems.
