I am going to do one project in labview my requirement is to control the stepper motor in following way
while pressing one button in front panel the stepper motor should run in one direction in less than 30 RPM continuously. I have seen in USB 6008 specification we can only send digital I/O at 20mA. But, my application require minimum one kg -cm torque, for that the stepper motor that I am having will draw more than 20mA...(probably 0.5 to 1 A)
and I don't know what exactly the stepper motor driver will do... Can anyone elaborate the function of stepper motor driver ...? Can stepper motor driver amplify the current pulses (digital output) to produce required torque?
