Hi Jazz,
I am newbie to cnc and stepper world. I have gone through various forums for power supply rating for stepper motors, but could not understand.
I am using a 18V-80V and 1.2A-7.0A rated stepper driver. and the
Stepper specs are
Ph. Current : 4.0 A
Ph. Res. (Ohm) : 0.85
Ph. Inductance : 3.8 mH
Holding Torque : 32 Kg-cm
Detent Torque : 1 kg-cm
Rotor Inertia : 680 g-cm2
Lead Wires : 4

rated voltage is 3.4V

I need 3Nos of stepper motor for my cnc. Now my question is what should be the rating of power supply if I am using single power power supply for all the three motors.
Can this power supply be used for the stepper drivers
800W-70V-11-4A-CNC-Switching-Power-Supply

Thanks
