need technical information
for a stepper motor with this feature
Type: bipolar / (unipolar)
Current: 2.2 A (3.0 A) / Phase
Holding torque: 1.65 Nm (1.3 Nm)
Resistance: 0.9 Ohm / Phase
Inductance: 2.2 mH / Phase
Wave diameter: 6.35 mm
Wave length: 19 mm
and Driver with a 4 ampere used l6203 chip
What are the characteristics of power supply that I use with only 1 card driver 4A + single stepper Current: 2.2 A (3.0 A) / Phase
-----------------------------
and what are the characteristics of power supply that I use with 3 card driver 4A + 3 stepper Current: 2.2 A (3.0 A) / Phase
i ask this because my stepper heats more then 80 degree when i uses 6.8A 22V in 1 card driver and 1 stepper
