HDD spindle motors

Product image of HDD spindle motors

HDD spindle motors are crucial components that power hard disk drives (HDDs). Because they directly impact storage capacity and processing speed, strict rotational precision and low NRRO (non-repeatable run-out) are required.
MinebeaMitsumi HDD spindle motors utilize our proprietary high-precision FDBs (fluid dynamic bearings) to ensure stable rotational accuracy and low NRRO. Furthermore, our integrated in-house FDB production system, from design to manufacturing, enables rapid and flexible support to meet advanced and diverse customer requirements.

Applications

  • HDDs (hard disk drives)
