Armature, Bar.
An armature in a dynamo or motor whose winding is made up of conductors
in the form of bars, round, rectangular and of other sections. This type
of armature conductor is objectionable as Foucault currents are produced
in it. It is found best to laminate or subdivide low resistance armature
windings.
[Transcriber's Note: Foucault currents are also called eddy currents.]
Armature, Bipolar.
An armature in which two poles are induced by the field. A bipolar field
magnet produces a bipolar armature.
Armature Bore.
The cylindrical space defined by the pole pieces of a dynamo or motor
within which the armature rotates.
Synonym--Armature Chamber.
