You quoted me making a comment from a different angle. Are you asking me a question, just talking, or did you misunderstand my comment? Google is your friend...thermal time constant, waste energy, motor efficiency. if you put 6 amps of work in without a load do the amps just disappear?
It was a comment directed at you.
I have a motor that runs hot on the track when set to 5A no load, and a different motor that runs cool on the track when set to 6A no load. No-load current draw is not a good indicator of loaded efficiency, so setting to a universal 6A no load setting for thermal reasons is not safe advice.
