Abstract

Disclosed is an improved spindle motor stator design with a smaller stator stem width for easier spin-up using inductive sense algorithm. This stator design enhances the sensitivity of winding inductance to motor magnet polarity and makes it easier to detect rotor position. This applies to all hard disk drive spindle motor configurations as long as inductive sense algorithm is used for spin-up.
