Abstract
We have developed a silicon steel core printed wiring board (PWB) for a highly efficient and low profile spindle motor, stator. This PWB incorporates stator coils and circuit patterns that realize a thinner hard disk drive than is possible with conventional coiled wiring technology. The thermal reliability test and an evaluation of power consumption of motor showed that this board-embedded structure is feasible for mobile storage devices.
