inverse of inductor

hello,



i'm looking for expressions relating to hydroelectric alternators. In an hydroelectric alternator, are there actual words which designate the inducting coil (the polarized "inductor", which is generally the rotor), and the inducted coil (which outputs an induced current, generally the stator) ?



Such words exist in French : "inducteur" (the "inductor") and "induit" (the "inducted"), that's why i'm wondering if they exist in english as well.



I'm looking for something along the lines of "inductor" and "inducted".



thanks.

The generally accepted terms are "field" for the inducting coil and "armature" for the coil(s) from which electrical power is taken. Hope this helps. ARM

thank you for the prompt reply. i still have a question though. can i use "armature" even if it is not rotating (in the case of an alternator for example, where the rotor - the field - is polarized, and the stator - the armature- outputs current)? thanks

Yes, certainly.

The terms "rotor" and "stator" refer to physical characteristics, the rotating component and the stationary component respectively. The terms "field winding(s)" and "armature winding(s)" or just "field" and "armature" refer to their electrical functions.

A DC motor or generator will have a stator that is the field and the rotor will be the armature. Power is limited by the size of the brushes and commutator.

An alternator (AC generator) will have a rotor that is the field and the stator will be the armature. (less current in the brushes and slip rings)
