基于力控制的磁悬浮硬盘驱动器研究

Study on the Magnetic Levitated Hard Disk Drive Based on Force Controlling

提出了基于力控制的磁悬浮硬盘的概念 ,介绍了力控制磁悬浮硬盘的基本工作原理和结构设计。对差动控制工作状态下系统的受力情况进行了分析 ,推导出了其主要参数的计算公式。还介绍了力传感器的工作原理。

The paper initiates a new conception of magnetic levitated hard disk drive based on force controlling. The principle of the magnetic levitated hard disk drive based on force controlling and its structural design are also introduced. The force analysis of the system under the differential controlling circumstance and calculation formulae for its main parameters are given. At the same time the principle and the structure of the force sensor are discussed.
