We have always used the term rotor for the portion of an electrical machine that rotates (as opposed to the stationary part "stator"). For linear motor designs the stationary portion is still the stator and we have used the term rotor for the "moving" portion. Now we have a EE drives engineer that would like to use a different (more accurate) term for the moving portion. In this particular instance, the moving portion consists of permanent magnets, so I'm not sure the term armature is entirely accurate. I have seen the terms like; forcer, magnet track, and magnetic movers used and none of them seem quite right. Any suggestions?
