摘要

通过对体积约束、磁约束和电约束动圈作动器的分析和数值算例，证明了动圈作动器在访问时间和耗散功率上存在全局最优。给出了一个简单的访问时间和功率的迭代计算方法。对于一个典型的圆盘直径为5.25的磁盘驱动器和一个分裂磁线性驱动器，通过数值计算得到了最优解。讨论了为分析所作假设的有用性。

Access time minimization of a moving coil actuator with volumetric, magnetic and current constraints

The existence of global optima for access time and dissipated power is demonstrated by analysis and numerical example for a volume constrained, magnetically constrained, and electrically constrained moving coil actuator. A simple iterative procedure for access time and power is given. The optima are illustrated by numerically obtained plots for a typical disk drive with 5.25 in diameter disks and a split magnetics linear actuator. The usefulness of the assumptions made for the analysis is discussed.<>
