BLDC HDD SPINDLE MOTOR DRIVER DOWNLOAD

On the other hand, the motors of the hard disks called “spindle motors” must be able to generate enough torque so the magnetic platters could rotate at the desired speed. I’ll go ahead and bookmark your site to come back later. No offense intended, but what’s your educational background? Francisco Hi, thank you for your kind words, you may translate and publish it, with linking to our website as original source. Yes, you should be able to run your BLDC with a controller. However, you’re not in luck, because driving that motor isn’t going to be as easy as you hoped.

EE Enthusiasts: hard drive spindle motor question.

As you might have noticed in spinxle second photo, I attempted to solder copper wires to the connectors. Tue Mar 13, Yes, you should be able to run your BLDC with a controller. This was insufficient for the larger spindls drive motor, so I briefly shorted out the sense resistor during startup. Distorted Sine output from Transformer 5.

The last class I took that had anything to do with motof was an automation course where we built our own automated, continuous loop, cells using Micrologix programmable logic controllers http: The plastic of the connector will likely melt and make a mess, and the amount of exposed metal available is not that great anyway. It usually isn’t accessible, so my guess is that it is here to help implementing a sensorless algorithm.

This stuff is very tiny and it is challenging to keep a steady hand when doing this but I don’t think that is the cause of this. Do you have any recommendations for one?

Ah, that drive’s older than I thought. You could in theory use the FG output to do closed-loop control of the motor speed using a separate microcontroller.

Implementing ramp parking system solved this issue completely. My Arduino Uno arrived and it became quite obvious that I need to learn some more about electricity before I can start controlling things with it. I need to get some of that smaller wire.

Equating complex number interms of the other 5.

Dec 248: Sun Mar 11, 6: This new hobby of mine really doesn’t have much room in my budget but it excites me to learn about this stuff to the point where I have pushed it more than I should.

Stator core is rigidly tied to the hard drive casing.

It’s only used for feedback sensing of the motor speed, and can probably be ignored for your application. These bearings work great for their design application, but they have one major caveat: Remove the flex cable entirely and solder to the motor wires directly.

In this way, hard drive platter s rotates together with the spindle mogor.

Related to source pull simulation for rectifier 0. Solder to the connector itself.

Fri Mar 16, 4: Jul 1, Posts: I know that ohms are resistance and I have a chart to figure out what the bands on resistors mean but I’m still trying to figure out why I’d need one on the 5volt output of the Arduino Uno for an LED. For mottor all HDDs, the motor is designed to spin counterclockwise; spinning in the opposite direction will rapidly damage the FDB.

Thank you, Fixxxer P. Everything was just too small for me to work with and I had no such luck.
