Is high inductance ever a good thing in a stepper motor?
I have a 6040 CNC mill that came with three nema 23-style 76mm steppers with the following stats:
1.8 step angle
6.6V
3A
2.2 Ohms
8mH
17kgcm
4 wire
I'm currently using a 24V power supply and the motors stall when I have the speed set above 1400 on Mach3. I've heard this could be because of the high inductance (8mh) of my stepper motors, and was thinking of using a 36v power supply or swapping the motors (or both!)
Is a motor with a high inductance every helpful in a CNC machine?

As a follow up to post #2.
Slightly longer at 82mm

The rest of theres looks a bit crap.

This driviver version highly reliable

60v 600w version of this will run 4 motors all day long (search around to see if can find more local first).
All these combined will see you able to run very rapid.
If you want to be 'conservative' but quick 'enough' then as an alternative:

Same motors

48v 600w version.
*With 3 of these 4A motors you want a minimum of 8A power supply*.
10A preferred which will cover up to 4 motors ie: 48v/480w+ or 60v/600w+ or 80v/800w+ etc.

I use toroid transformer 62 vac 30A, it is simple and reliable, motors run good ...
