Nice looking servo motor with driver built in! This should work for 3d printers to!
$350 per motor plus $380 for a 4-axis control box? Uhmmm… no thanks.
There are some lower-cost stepper + encoder + driver units available, but they are still many times as expensive as regular steppers + drivers.
Servos are actually more suitable for milling than they are for printing because a mill should always have an appreciable amount of force against it (at least when it matters) that will arrest the jitter. This is not true of 3D printing.
That’s also a bit larger than a NEMA 23 motor and it has a 100W rating per motor. It’s not even NEMA form factor compatible.
Hopefully something comes of this project: https://hackaday.io/project/11583-odrive-high-performance-motor-control
another example of this being easy but relatively expensive, Teknic ClearPath motors have NEMA23 mounts and start at around $250 each. http://teknic.com/products/clearpath-brushless-dc-servo-motors/
Another down side for the ClearPaths is they do not offer metric shafts, off the shelf at least.
