Hard Drive Motor Wiring

It is powered usually by a 4 wire plug the connections from hard drive to the rest of the computer circuit. If i give a voltage to any of those pin the motor just jerks.

Even early hard disk drives also used steppers but nowadays hard drives have replaced the teppers with voice coil servo motors.

Hard drive motor wiring. The stepper motors used in 5 14 floppy disk drives usually move the readdrite head using wheel and spring mechanism which works quite. I have some dumb harddisk. Hard drives work by spinning platters full of magnetized data while a readwrite head very quickly harvests or changes bits as needed.

A serial ata hard drive may also have a third connector for legacy pata power connections. I know about normal motors like with magnets and stuff and how it works but beyaond normal 2 wire stuff i got. I know nothing on motor like this.

Hi every one i m need to use hard disk spindle motor for my proj bcos it gives constant high rpm like 5400 or 7200rpm. Pls tell me how to run them. Floppy disk drives use stepper motors for controlling readwrite head position.

Is it possible to use normal power transisotr to drive those motors. Sata interface the serial ata sata bus is defined over two separate connectors one connector for the data lines and one for the power lines shown left. I recently found some old and newer hard drives too damaged to be repaired for normal pc use now i took one apart for parts such as the motor inside.

You can use the original pcb that comes on the hard drive to power the motor. You will have to run a couple of wires to ground on some hard drive to trick the pcb in keeping the motor running. Samsung harddisk motor comes with 4 wires and seagate harddisk motor comes with 3 wires.

Brushless hdd motor driver from 9v and painters tape. Some hard drive pcbs will allow the motor to spin continually and some will stop after a certain amount of time. The pata power connector may be used in instead of the sata power cable to supply a connection which is more rugged and.

The motor is known as a three phase brushless motor that is somewhat similar to a stepper motor which is another type of motor fond in hard drives.
