Abstract
A high-speed magnetic-fluid bearing spindle motor for hard disk drive is introduced. Some design challenges and considerations of its load capacity, stiffness, power consumption, lubricant leakage and shock resistant capability are addressed. The prototypes were fabricated and the test results of the prototypes are presented and discussed. The results show that the magnetic-fluid bearing spindle motor is very promising for use in future hard disk drives
