Click to expand... And you can screw up the paint job of the refrigerator door or a steel-clad passageway door trying to get them off. I have to actually work on auto-starting it before I can really use it but just making it start in less than half an hour of significant effort would already be Scraping hard drive motors You need: Torx screw drivers (especially T8) common screw drivers Technique: No special attentions needed. http://tuiconverter.com/hard-drive/hard-drive-driver-x60.php
Then you simply write the data you want send to parallel port data pins to this I/O address. Older drives have used magnetic hall or coil type sensors for sensing the rotating speed. This makes it possible to have both drives to be jumpered as drive A and one drive works in this way as A and another as B. Anyway I placed a black DOT that I will refer to as terminal #1, the others from left to right are #2,#3, and #4. http://forums.parallax.com/discussion/119874/hard-drive-stepper-motor-with-high-speed-spin-up-circuit
Make sure that the electronics does not need to detect the disk in the drive to be able to move the stepper motor. The answer is that disk-drives have many expensive components and you can get old bad disk-drives freely or very cheaply. How are spells made permanent in 5e?
At certain driving frequencies near the resonant frequency of the motor, there will be some audible vibrations, and the motor may not even move - it will just sit there and Anyway those signals are always TTL-level signals. The RdsOn is a little high, but for this demo it worked out fine. - Caution when interfacing the Tach, the output is 12V and should be placed through a voltage How To Run A Hard Drive Motor Most platters these days are glass - be warned.
The circuit pretty much shuts down at less than 6V and I'm afraid to crank it up past 15V because it spins so fast, I'm afraid the platters will easily remove Powering A Hard Drive Motor This requires you to know somethign about the motor characteristics too. Does that sound right? Loading...
I expect that the drive is jumpered to be as drive A. Run Hdd Motor Without Extra Circuitry Best regards, Luciano Reply With Quote - 10th January 2006,11:37 #9 forgie Guest Man I feel stupid for not even getting out my multimeter in the first place... Even tried 3 TIP127 High Side Switches (controlled through 3 TIP122) coupled with 3 TIP122 Low Side Switches (through Arduino UNO).Didn't Work. Three distinct semi sinusoidal waveforms (not pure sinewave AC) that come in at different times (or degrees) will causes the rotor to rotate with the changing (alternating) magnetic fields of the
Use BD139/140 or BD237/238, and calc the resistor.

Usually there's example code as well. How about using hard disk stepper motors ? Hard Drive Stepper Motor Arduino
No, create an account now. All the units I have dismantled are permanent magnet brushless dc motors. For what I'm trying to do, a hard disk chassis is actually a good platform to build on, which is why a hard disk spindle motor seemed the obvious choice. Check This Out The time now is 16:11.
In the schematic I have included an "ENABLE" and a "TACH".

Even early hard disk drives also used steppers, but nowadays hard drives have replaced the teppers with voice-coil servo motors.
There is only experiment. Best regards, Luciano Last edited by Luciano; - 12th January 2006 at 09:28. amiir made it!

How To Run Hdd Motor With Battery Spindle motors Most drives have several platters that are separated by disk spacers and clamped to a rotating spindle that turns the platters in unison.
The platters need to spin at a constant velocity for the data to be read so the "steps" produced by a stepper motor would not work. both codes are giving vibrations or very jerky motor movementReplyDeletePlayer3February 1, 2017 at 8:58 AMI'm curious about something before I go to try any build this myself.... http://www.piclist.com/techref/io/stepper/wires.htm Duffer ▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔ Any technology, sufficiently developed, is indistinguishable from magic.· A.C. this contact form Working...
Hot Network Questions Is it ever worth asking a question if you know the answer is "no"? However, there are different limits for different motors. and it would be nice to achieve about 7000 rpm like the original driver.So what do you think? Stepper motors are same types as used in floppy drives, though the number of steps/revolution might be higher.
Using a wall plug as a 12v source instead of the batteries will work right? I had a couple of western digital hard drives lying around that were DEAD. Pin Function Direction 1 GND 2 High density sel ??? 8 Index pulse from drive 10 Motor on A to drive 12 Drive select B to drive 14 Drive select A
