The Implication of Three-Dimensional Mesh Generation on the Calculation of Mechanical Forces in Magnetic DevicesMany magnetic devices are designed to convert electrical to mechanical energy, or vice-versa and thus an accurate prediction of the generated forces and torques is fundamental to the design of the device. There has been considerable work done in understanding both the major mechanisms involved in force generation and torque calculation algorithms in a numerical system, i.e. in the presence of numerical error. up to the present time, these comparisons have been made on problems which could be solved using two-dimmensional analysis systems. This has largely been because three-dimensional solutions were considered too expensive to use as everyday design tools. |
