I am looking for a motion control solution. I want to advance a carriage on a ball (or Acme) screw or screw jack with a resistance up to 3,000 lbs force. The ball screw diameter will probably be about =BE" to 1" in diameter.
I have not yet decided on what method to use. I am considering:1=2E DC motor with pot to adjust the speed (least desirable method) 2=2E Gear Motor with encoder 3=2E Stepper Motor or Servo Motor with Driver and Controller using: =B7 Computer Interface or =B7 LCD and basic pushbutton interface on the machine itself.
I need to do the following:1=2E Set linear speed rate from 0.001 in/min (or slower) to max speed for return to home position 2=2E Set a home position 3=2E cycle the carriage back and forth X inches about the home position Y amount of times. 4=2E go to X inches and return to home 5=2E have safety limit switches.
I will also be collecting data from 2 LVDT's or Digital indicators and Force from an S-type load cell. One of these LVTD's would be to record the carriage position. This could be eliminated if I could calculate the position to 0.001 inches. These would be in a separate Data Acquisition system but if I could group it all together with the controls that would be great.
I don't have much experience in this field and was looking for as close to a canned package as possible with the flexibility to design my own interface.
I am not an Electrical or Mechanical Engineer. I need this for an inhouse project but may consider selling the system if things work out. What kind of costs am I looking at and can anyone recomend a consultant or company that can help.
