Abstract:
A spindle motor for use in a disk drive having a rotatable head stack assembly, the spindle motor comprising:a spindle motor hub having an axis of rotation; a magnet radially attached about the spindle motor hub; and a spindle motor stator including: a stator rim; and a plurality of stator teeth arrayed about and internally extending from the stator rim towards the axis of rotation, the stator teeth being sized to fit about the magnet in operable communication therewith for rotating the spindle motor hub, a first two respective ones of the stator teeth being spaced apart along the stator rim to form a first spacing between the first two respective ones of the stator teeth to allow the head stack assembly to pivot between the two respective ones of the stator teeth, a second two respective ones of the stator teeth being spaced apart a same distance as the first two respective ones of the stator teeth along the stator rim to form a second spacing between the second two respective ones of the stator teeth opposite the first spacing.
