It is far more than that. What you are calling a DC motor is a brush type motor. It is a universal motor and will run on AC or DC power. The brushless motor runs on AC.
None of this is new. What is new is far more efficient electronic ways to covert DC, battery power to AC alternating current. Far as Edison verses Tesla the duel was Edison vs Westinghouse. Current is better transported at high voltage. AC can step up and down the voltage with a simple transformer. DC thus is limited to short transmission. Edison set up his first generators in down town Manhattan and was still supplying DC current to businesses in lower manhattan. I spoke to a guy working on an elevator in downtown manhattan about 15 years ago. I asked what he was doing. He was converting that elevator from DC to AC. So 15 years ago you could still purchase DC current in lower Manhattan. My uncle's printing plant was running on DC. His equipment was bought by my grandfather. The best printing presses were made in Germany??? Heidelberg-I think. I expect they were purchased before WWII. Perhaps, because of foreign competition, because of obsolete equipment the plant went out of business. The equipment, still working was sold as scrap.
