The higher the inductance, the lower your top speed will be. You use the motors rated current, and use the formula V = Square root(mH) x 32 for your voltage. With higher inductance, you want a higher voltage. Higher voltage gives you more torque at higher speed. Since the G540 is limited to 50V, the voltage will limit your speed, as, ideally, you'd want a 64V power supply with a 4mH motor.
