What I am trying to say is that there is no motor in mag drives: an electro-magnetic field spinning an impeller in a Fe jacket. Impeller is the only moving part. Yes, the flow will slow down because the impeller cannot maintain the RPMs because of the building back-pressure, but there is nothing to burn out?
