Talk:Growler (electrical device)

Stator vs rotor

I've never used one of these items, but it would appear that there is a mistaken point here...stators are static and do not have slots or segments in general....those are on the rotors.

in both cases, a short in the coil would cause the vibration noted, as it would produce an isolated segment with a closed loop. 2001:5B0:28FF:EF0:0:0:0:3B (talk) 12:05, 6 May 2013 (UTC)

It's applied to the armature, which is a broad term for an electromagnetic construction that can be either a rotating rotor or a stationary stator. Rotor is often seen as a synonym for armature, through their common use, but armature is actually broader than this. Even electric bells and relays have armatures.

Rotors are more commonly tested, because (owing to their more confined windings and poorer cooling) they're what fails most often. Many growlers, like that illustrated, just wouldn't physically fit onto the poles of a stator. I've seen them used to test field coils off the stator though, by using a piece of scrap core as a temporary test armature. Stators still have slots and segments though, at least to the level that a growler cares about. Andy Dingley (talk) 12:46, 6 May 2013 (UTC)
