Greetings! My name is Wren and I’m a Biomedical Engineering student in the graduate program at the University at Buffalo! I have a question with regards to the motors required. The third item on the bill of materials (BOM) calls for a type Nema 17 length 34mm Holding Torque 21.57 N.cm motor. You guys provided two links in the BOM for the motors however I was not able to find that exact motor. I was able to find the same exact motor but with a holding torque of 28N.cm. Will that suffice? Thank you!
I assume the links you are referring to are to the Thor repository wiki (currently deprecated).
The links you will find in the BOM of the project website are up to date and will take you to the correct model.
Anyway, the links to the components are for convenience, if you prefer to buy from another store just check that the torque requirements are at least 26N.cm and the motor consumption is around 0.4A powered at 12V.
