That motor looks like a standard Nema 16 39mm, the 57BYG is a nema 23 and is a lot larger.
We also stock a whole range of Nema 16 motors as well, but you will need the full specifications the torque details.

Yup, Like the one on your site, it was the closest to the steppers that were shown in the images for the machine plans.
I have just had an email back from the seller and he has said that the motors that the machine was designed for was the TANDON KP4M2-203, (drawing attached), as far as I can find out these were originally used in TANDON 5.25" Full Height Floppy Disk Drives!
I was trying to find a Stepper motor(s) with better operating specs and holding torque but with the same 31mm mounting hole centres.
I want to make sure that the motors will drive the machine, Alu construction and safely control the combined weight of the z axis and 230v 5,000-30,000RPM Hobby Die Grinder that weighs about 1Kg.
Any thoughts appreciated
