Abstract
The novel electromechanical milling principle is a solution providing reduced energy consumption with milling beads directly moved with a time- and local-variable magnetic field, which is generated in a working chamber by an external, electrical excitation system. Hence, the main design parameters of such machines for electromechanical milling (so-called EMZ plants) must be derived from the time- and local-variable magnetic flux density, the resulting vector gradient and the electromagnetic force distribution in the process room. For the calculation and optimization of these distributions we developed a numerical model on the basis of the commercial software tool ANSYS Maxwell®. We verified this model with experimental measurements of the electromagnetic field in the process room. Furthermore, we have studied the influence of the excitation system design on the vector gradient distribution and discuss selected results in this paper. The study identifies potentials for the further improvement of electromechanical units built in the past.
