now my problem is to use a simple driver.
open "matlab>help>demos then search for "stepper motor drive" you will find a model that contain: signal builder, Driver, stepper motor, and scope.
right click on the driver then press "look under mask" you will find the circuit of driver, there are many components that I don't know what it's used, so try to help to understand it.
I hope also that you can gave me another three simple drivers
also, can you explain "Linear speed control of stepper motor"
thanq for replying...
