I am trying to figure out the power supply I will need to run four identical stepper motors in bipolar parallel mode. The amp rating/phase of a single motor is 5 amps when used in bipolar parallel mode. My drivers are Gecko G201's. In the 201 manual it says I will need 67% of the rated phase amperage from my power supply. Since I'm running four motors, does this mean I need a power supply rated at 13.4 amps? (.67 * 5 * 4). I've already calculated the voltage of the power supply from the Gecko formula: 32 * sq rt mH to be about 40 volts (32 * sq rt of 1.65mH). This is less than 25 times the rated voltage (1.9v) of the motor, so I think I'm OK with a 40volt power supply. So should I stay at or under 13.4 amps for the current supply? As you may guess, I know next to nothing about electronics. I'm just trying to plug in the specs from my various components to determine the power supply I need. Thanks for any help.
