摘要

This article deals with problem solution affecting the magnetic field of permanent magnets by change of their position. This article proves the possibility of magnetic field influence on individual construction parts of a positioning mechanism. The first part of the article deals with the problem of magnetic surface levitation of diamagnetic object and with the description of principle of mechatronic positioning mechanism. Specifically, functions of individual construction parts in term of mechanics are described. Positioning levitating mechanism uses for magnetic field generation the matrix NdFeB 32, which is the matrix of permanent magnets arranged in a particular configuration. Linear actuators working on piezoelectric principle were chosen for magnets positioning. The next part of this article deals with numerical solution of magnetic field using calculation software FEMM, for five different configuration positions of permanent magnets. Using the postprocessor mechanism, outputs, for magnetic induction, for lines of force and for vector fields of each position, are subsequently created. In almost the last part the calculation of energies and forces acting in direction of magnetic field axes X and Y is done. The conclusion involves a summary of the possible influence of magnetic field by the change of magnets position and its subsequent influence on the levitating pyrolitic graphite, which is represented by the diamagnetic object.
