The
technician who replaced the motor said that it may have failed because
we didn't have a dedicated circuit. Might this be true?

No, it's not true. Furthermore, that "tech" needs to be reported for giving
out false information on a whim and not backed by any evidence to the
contrary. Whether it's a dedicated ckt or not in your case, it's totally
irrelevant. I'd send them a nastygram about their phoney tech. He has no
business making such statements off the top of his head and without knowing
it to be at least likely from his observations. In other words, he's a
pompous idiot.

From reading your post, including your responses about monitoring the
voltage with a meter, it's NOT a problem.
