Abstract

This study is for a design of a spindle motor for 1.8 inch hard disk drives(HDDs). Equivalent magnetic circuit model is applied for a basic design of the motor, a specific configuration design and magnetic distribution characteristics are confirmed using finite element analysis. Besides, thrust forces generated between rotor and stator core and thrust pad are calculated for pressure analysis of fluid dynamic bearings.
