Help Needed
I am trying to find products that will allow me to monitor current in a stepper motor. The stepper motors work on 48vdc supply and the currents can range from 30mA to 6A as was looking at using Hall Effect technique as it will not interfere with the running of the stepper motor. Then the analog signal will most likely need to be smoothed through a filter, amplified and converted into a digital signal and interfaced with a pc to be run using either Delphi or visual basic to monitor the changes? Any help with design or relevant products would be much appreciated.
Cheers Chris
