Abstract :
The topology optimization of electromagnetic (EM) systems considering the effect of the magnetization direction in the magnet is investigated using the finite element method. The density method is used for topology optimization and continuum design sensitivity analysis is used for the sensitivity of EM systems. Also ANSYS is used for analysis. The force of a magnet is divided into two components of x and y direction in the rectangular coordinates. And the topology optimization of a c-core and a brushless dc motor are obtained.
