Yes, for sure. > Further, a back-emf is produced, which confirms it is > electromagnetic. No, for sure not! If the motor runs, using electric power and turning it into mechanical energy, then it must produce a back EMF, whether it's fundamentally an EM effect, a heat effect, or the consequence of magic gerbils living inside the ball bearings. No back EMF => no electrical energy consumed => it's not an electric motor, whatever it may be. Um ... or anyhow, I think that's the case...
