I had Koldwaterâ€™s older version of Motor Control Tutor from around 1999/2000. I think it came bundled with some other PLC or VFD Tutor software and the old version of Constructor, their ladder diagram building software. I thought the software was neat and the interactive diagrams made it easy to understand the sequence of events by seeing what takes place with things like the Star-Delta and two-step part-winding starters. Much more interesting than reading a plain black and white Audelâ€™s Electric Motors book or squinting at pages in the American Electricianâ€™s Handbook. I remember saying to myself after using one of the tutor programs for the first time, â€śthese guys nowadays have it made.â€ť
Their software was a little pricey even back then, but I think if you have the coin, it would be a good investment in yourself.
Have you checked to see if you can download some trial versions of the stuff your interested in before purchasing?
