Analysis of a Hydrodynamic Bearing of a HDD Spindle Motor
Apr 19 2004Once the viscosity and clearance of hydrodynamic bearings of a HDD spindle motor are determined finite element analysis of the Reynolds equation is performed to investigate the static and dynamic characteristics of hydrodynamic bearings of a HDD spindle motor at elevated temperature It also shows that the variation of clearance due to
Hard Drive Data Recovery
Dec 07 2016Failed Spindle Motor Bearings Bearing issues can cause problem that range from induced noise into the subsystems all the way to being completely frozen The latter is a very complex procedure requiring the media stack to be transplanted into a donor drive
Hydrodynamic bearing HDD
The Bearing of Hard Disk Drive Spindle Motor The speed of magnetic disk rotation is about 5400 7200 10000 or even 15000 revolutions per minute that means the necessity of using qualitative bearings Earlier the ball bearings with balls made of metal alloys or ceramics were used for HDD production In the modern hard drives the liquid (hydrodynamic) bearings are applied
S M A R T attributes
General throughput performance of the hard disk Indicate problem with motor servo or bearings 3: Spin Up Time: Time needed by spindle to spin-up to full RPM Indicate problem with motor or bearings Critical attribute: 4: Start/Stop Count: Count of start/stop cycles of spindle This value does not directly affect the condition of the drive 5
Rod end spherical bearings
Used in aircraft components such as wing flaps engine and wing mounts and hatches rod-end spherical bearings function as joints These bearings are also used extensively in helicopters trains automobiles electric power plant construction machinery ships attraction equipment and space-related products
Dynamic Characteristics of Hard Disk Drive Spindle Motors
In this paper the frequency-forced responses of hard disk drive spindle motors supported by both ball bearings and liquid-lubricated spiral groove hearings (SGBs) were studied experimentally It is found that both shaft rigidity and disk flexibility have great effects on the natural frequency of the spindle motor conical (rocking) mode
Thinner HDD Motor Design
The thickness of the spindle motor built in to the HDD is 70% to 75% of the thickness of the disk drive making the motors of 7 mm HDDs approximately 5 mm thick The biggest barrier to successful thin motor design has been the assignment of sufficient space for magnetic circuits and bearings
