For the current, you need to figure out how you are going to wire a motor, and add up all 3 of them. If I wire these in parallel (half-winding) mode, i'll be drawing all 4 amps that the motors are rated for. Take 67% of that number, add up all 3 motors, and I get about 8 amps. If I am figuring something wrong, please let me know.
