Design Optimization of Linear Synchronous Motors

Linear motors are strong candidates for manufacturing automation applications requiring high-performance direct-drive linear position control. Unlike rotary motor drive systems, linear motor drive systems do not require rotary-to-linear transmissions, such as belt or screw; hence they usually provide higher performance. With increasing usage and higher demands for better performance, linear motor design has become an ever important subject. Since electric machine design process usually involves several design objectives, multi-objective optimization technique is naturally a suitable choice to address this challenging problem. This book provides a basic framework of designing linear synchronous motors by covering three major topics: (i) magnetic modeling, (ii) optimal performance assessment and (iii) multi-objective design methodology. Two selected topologies of linear permanent-magnet and linear variable reluctance motors are then considered for manufacturing automation applications. This work should help provide some analysis tools on this exciting subject, as well as should be useful to any professionals in electrical machine design, numerical analysis and optimization.
