Things you can make from an old DVD drive #2 - Step a stepper mo...



In this episode I have disassembled the head motor assembly and fitted the two stepper motors to a block of wood so that I can play about with them. All I have done is extended the wires to a breadboard so that I can manually step the motors using a couple of AA batteries.
Thomas Kim does a good series of videos on using stepper motors. Here is an example https://youtu.be/yD4YEwG-3VA
and another https://youtu.be/-NpzRkXfn3Y
If I can find some suitable motors I may try some of his ideas in another video some time.

Here is my video https://youtu.be/n83utWnYCVE testing a driver board I bought on eBay which includes an infrared remote control. I also had a question from somebody else about making one from scratch and I gave them a link to one of Thomas Kim's videos on the subject that you might find interesting https://youtu.be/Vc2XRVJ9n1o.

    Do you have many DVD drive? or you just use the parts from the other dvd drive?

    Look into bi-polar and Uni-polar stepper motors in Wikipedia, they are each driven in a different way, and you can buy a easystepper board for a few dollar on Ebay which will probably drive the one you are having trouble with, which may be a bipolar.

    Hi Joseph Massimino, you left a comment but have replies blocked so I assume you don't really want a reply but for the benefit of other people watching this video I will add this link to the video I uploaded yesterday http://youtu.be/n83utWnYCVE testing a driver board I bought on eBay which includes an infrared remote control. I also had a question from somebody else about making one from scratch and I gave them a link to one of Thomas Kim's videos on the subject that you might find interesting http://youtu.be/Vc2XRVJ9n1o

    Heres a vid I did using a micrcontroller and a dual full H bridge to drive a cd rom stepper motor, most of the work I did was in the software, this is pretty much a minimum part count to do this, just the microncontrller and the H bridge chip, which is a L298.  https://www.youtube.com/watch?v=KwS0SUSeJpw The red board at the back connected up is just my programmer its not doing anything in the vid.

    He worm gear stepper is bi polar you need to switch the polarity of the wires every other step i belive look up manual bipolar stepper motor

    Try inverting the polarity on a certain set of pins/wires for the screw stepper motor. It works for mine.

    I think the screw motor is a 2-phase AC motor. If you turn the screw manually, you will feel no cogging, from permanent magnets, because there aren't any. Try powering one set of windings with about 6 volts AC and the other set with 6 volts AC, through a capacitor, to shift the phase.

    Ik this is an old video, But that second motor the worm gear one (atleast I think thats what its called lol) how would I get it to keep turning in a constant motion, and for example would it be able to push out a thin line of plastic as it turns.

    Thsese are brushed DC motor and NOT Step motors.

    I guess, the only way to find out is if you open it up.
