Abstract
- Abstract: The focus of this paper is to show that the magnetic force generated by a linear actuator may be enhanced through the optimization and design of the devices air-gap magnetic field distribution. Specifically, the use of a periodic ladder structure is proposed for magnetic field manipulation, and a simplified finite element analysis is adopted in lieu of a higher cost computational model. The optimal magnetic field distribution that maximizes the actuator force is then found via structural topology optimization. This force enhancement is explained using a Maxwell stress tensor analysis and validated through experimental studies. Finally, a periodic-ladder structure is designed for an equivalent optimal magnetic field distribution, and the linear actuator force enhancement is confirmed. [Copyright &y& Elsevier]
