Power Supply Question
Hi everyone,
I have a project that I'm busy with and I need some advice regarding power supply...
The machine in question has the following:
2 X NEMA 34 stepper motors - 6 A per phase @ 2.7 V, 0.45 ohm, 8.7 N.m holding torque , 6.0 mH inductance.
2 X NEMA 23 stepper mototrs - 2.8 A per phase @ 3.2 V, 1.33 ohm, 1.89 N.m holding torque, 3.6 mH inductance.
These motors are required to run at very high rpm, in fact as fast as they possibly can without losing steps. The nature of their application does not require much torque at all.
With this in mind I know that I'll need decent drivers that can operate at high voltage supply - I've chosen to go with 4 X Gecko G203V's.
My question is what is the best method to supply power to these drivers? Do I use 4 individual power supplies or should I rather go for something like a toroidal transformer? I'm slightly worried about the back emf that will be generated by the steppers at high rpm...
Any other advice would be much appreciated!
