    But the price is higher and the inductance is higher

    The price is same or lower. You have shipping costs and eventually duty to pay. If you are saving on stepper motors, you will not go far with that build. The links i gave you are the cheapest in Europe

    Inductance is probably my biggest concern.

    This is the motor that everybody here uses for a step motor on their CNC. No surprises, works well at 70V. The motor you show has less inductance on paper, but how true is that...

    That was kinda my question. Is there anyone who have tested this/looked into it before?

    Edit. I see that cnc uk sells the steppers in a kit with a 36v supply. I asked if they would put on a 48v supply instead. According to the classic 32*sqrt(inductance) rule about 57v should be optimal. Why is they selling 36v supplies in their kits?

    Cause most people / not on this forum/ don't build their own power supplies. And a 70VDC non regulated 550W PSU for 4 motors is not exactly cheap or light to manage and ship. So they offer the typical stuff assuming if you are to build strong and fast CNC you are knowledgeable from where to buy and build the PSU
