    Stepper Motor problems...

    Thanks for the comments. If had the Munro instruments I would be using them, but I do not. I made two changes today, I converted to single step operation and I increased the time delay after selecting speed direction. It appears to be operating perfectly but I will give it a couple of days...

    This is for a museum exhibit and the aim is to replicate the Munro style of instrument.. This is their wind speed indicator and the wind direction is the same style. Thanks for the suggestions of alternatives but I am somewhat committed to what I am doing especially as I need to make six...

    Hi Bluejets, yes, I am using an Arduino and pulses from the head unit, I am using an opto device instead of a Hall device but I sure will look at those files for inspiration. K_E, The loss does not appear to be consistent and I count the steps up and the steps down which appear correct. The...

    The stepping is very slow so I doubt ramping is an issue. You are quite right that the stepper is maybe not ideal for the job and I would rather have selsyns to work with but I dont so steppers it is but thanks for the suggestions anyway. I have been thinking since posting that micro stepping...

    Stepper Motor problems...

    I am using stepper motors as indicator instruments in an anemometer project I have made. There is a problem in that the stepper motor driving the wind speed dial tends to loose steps, but only in one direction. Under ordinary circumstances the wind may vary from say 2 to 10 knots, when the...
