I can understand your comment. In fact its common knowledge that mechanical work adds to the heat model. My comments had nothing to do with your point and the differences and similarities between waste energy and mechanical heat, work together to create total heat but I made no connection to the concept. 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?
