But the price is higher and the inductance is higher

Inductance is probably my biggest concern.

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?Last edited by PotatoMill; 28-07-2016 at 08:18 AM.

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
