description: The given work is devoted to searching of optimal design of the conductive coil under permanent magnetic field for Lorentz force maximization. The research set the following goals: 1. Studying of the existing methods of topology optimization of electromechanical system. 2. Three-dimensional magnetostatic analysis for ideal permanent magnets of finite size (analytical solution). 3. Three-dimensional magnetostatic analysis for ideal permanent magnets of finite size (numerical solution). 4. Three-dimensional magnetostatic analysis for components of voice coil magnetic system. 5. Analysis of distribution of direct currents in continuum. The work was fulfilled on the premises of the educational research laboratory âComputational mechanicsâ. The geometrical sizes of the optical pick-up were taken from LG DVD-ROM after disassembling. Numerical results were obtained in COMSOL Multiphysics. As the final result of the given work it was provided 3-D model design of optimized coil with better objective function characteristics than the original one.
