I've never heard of a motor without back EMF. However, there is a company in Ireland launching a new type of motor that apparently does not experience back EMF.
Here is a video about the E-Orbo technology and how it does not experience back EMF.

My understanding is that the current/voltage traces should change when the system is under load. However, in the video it does not. Does that mean the system is not experiencing back EMF?
It seems these folks have a very interesting technology.
