What name is accurate for a linear motor rotor
What name is accurate for a linear motor rotor
(OP)
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?

I have seen different terms used for each of the components. We have converged on Primary Forcer and Secondary Track.

RE: What name is accurate for a linear motor rotor
Thanks. Are either of these terms indicative of whether the coil or the magnet is moving, for instance would the Primary Forcer be the stationary part and the Secondary Track the moving part? Or maybe the coil is the Primary Forcer and the magnet the Secondary Track no matter which is moving. . .
Best regards,

For us the Primary Forcer is the magnetic moving component and the secondary track is the stationary coil.

BINGO.
Those of us who use and sell liner motors call one piece the "COIL" and the other the "MAGNET" or magnet track.
Do this too Matt and no one is confused which is which. Either can move depending on your design.

Thanks, this seems as direct and to the point as can be.
