We have a carousel that we use to replicate filling lines at beverage plants. Basically it is a 2 foot diameter wheel that holds (14) 20 ounce bottles and rotates at high speeds. We are running tests at high speed ramp up, going from 0 containers per minute to 1,200 cpm in about .75 seconds. The problem is that our carousel speeds up very very quickly at first and then settles out. We would like it to ramp up at about 1 cpm per ms. Basically 0-1,000 cpm in one second. Our carousel is controlled via some sort of variable resistance module that has a dimmer type switch. Is there any product that we can get that would do the following?
I want to measure the voltage and current going to the motor for the carousel at given line speeds. So I would set our resistor to a point that will give us a line speed we want and then take a reading. Basically take a reading at every 100 cpm from 0 to 1200. I was hoping that there was some sort of variable resistor that I could program the current/voltage set points into. Then basically have it use those as a linear reference and ramp up through them in a given time interval. So it would give our carousel the 10 set points over the time period we want so that we can get a better linear acceleration to test with. maybe some sort of logarithmic potentiometer?
