    Could anyone help me find links to the exact motors mentioned in the materials list please. I have the websites that the original maker bought his from but I can’t find the motors with matching holding torque which is stated. I can find the similar ones with the same size but the holding torque is always a few above what it’s meant to. Any links to motors online would be much appreciated. Preferably an online shop that’s from the UK if possible.

    Many thanks

    Hi Jamie, i just asnwered your question at Thingiverse, but I’ll answer here again because I think this information could help someone in the future.

    For buying stepper motors all you have to look is the voltage (12V
    in this case), the rated current (I prefeer under 2A in order to control
    it with cheap drivers), the torque (depends on each articulation, but
    look at part list specs) and the size of the motor (in this project
    there are all Nema 17 with different lengths, also provided in the part
    list specs).

    There are many websites along the net and local stores that sell this kind of motors, as them (except the geared motor) are frequently used on 3D printers.

    If you want some links, these are the StepperOnline motors that fit with the specs listed here.

    Articulation 1: 1x Nema 17 40

    Articulation 2 & 3: 3x Geared Nema 17 121.2

    Articulation 4&5&6: 3x Nema 17 26

    I think that would be nice to have a list with the online shops that have Thor components in order to ease the shopping.

    Hope it helps!

    stepperonline sells on amazon (at least in the US) – maybe we could come up with an amazon list that has all the components needed for a Thor? the correct pulleys, the steppers motors, the metallic rods, etc .. ;

    I forgot to mention that, at least in this case, the more torque the better. So on equal terms of voltage, current and size if you can choose a motor with more torque do it.
    More torque means be able to lift more weight!

    Best regards 😉

    Thank you very much for replying, I’m a lot more confident know in what motors to buy. I hope to have something soon I can share with you and the group.

    Many thanks

    Hi Adrian,

    Thank you for noticing that the BOM links where not correct! 🙂
    I updated the motor ones. I’ll check the rest ASAP to ensure that every link works.
