Abstract

Applying boundary conditions such as directional forces or distributed forces provides a mean to simulate the effect of cutting forces on Permanent Magnet DC Linear Motors (PMDCLMs) to replace existing DC servomotors on CNC machines. The performance of such a model consideration has been determined utilizing electromagnetic finite element analysis. The model represents the orthogonal cutting forces using one axis of a working table holding a workpiece. The three-dimensional solid elements are applied for modeling the 3-D state of the field distribution inside the linear motor. Simulation of the cutting force is defined within a force data group of NISA finite element software. In addition, other boundary conditions, namely electric and magnetic field characteristics such as E-field, flux, effective power, and current density in the X, Y, and Z directions is applied. The implication of these motor performance changes is discussed. The static performance of the PMDCLM's secondary is illustrated.
