Brushless motor driver for disk drive motors

The motors all run pretty well - the hard drive motor is around 6000rpm with a 12V supply, and the ZIP drive motor is around 15000rpm (way too high for the original purpose!). You could in theory use the FG output to do closed-loop control of the motor speed using a separate microcontroller.

Hard Drive Stepper Motor - with high speed spin-up circuit ...

Oct 27, 2016  Don't throw away that DEAD hard drive just yet... I had a couple of western digital hard drives lying around that were DEAD. Initially I was going to just harvest the magnets from the drives, but I focused my attention towards the hard drive motor itself instead. On the left hand side of the image, I just soldered 4 wires to the back of the motor.

Hard disk drive - Wikipedia

A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.

Can I run a hard drive motor without additional drive ...

Answer 10 years ago. You can reuse an old hard drive brushless motor in several ways. 1. 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. Some hard drive PCB's will allow the motor to spin continually ...

Spindle Motor Failure Seized Platters - ACS Data Recovery

A common physical failure within certain hard drives is platter seizing. This is when the platters are unable to spin up, and the drive is inaccessible. There are a number of possible causes for this type of failure. The two main drive types where we see spindle motor problems are in external hard drives and laptop hard drives.
