Armature Current

Some articles on armature, current, armature current:

Armature (electrical Engineering) - Armature Reaction in A DC Machine
... In both the generating and motoring modes, the armature carries current and a magnetic field is established, which is called the armature flux ... The effect of armature flux on the main field is called the armature reaction ... The armature reaction demagnetizes the main field, and cross magnetizes the main field ...
Synchronous Condenser - Theory
... load on a synchronous motor increases, the stator current Ia increases regardless of the field excitation ... The phase of armature current varies with field excitation ... The current has larger values for lower and higher values of excitation ...
Electric Motor - Operating Principle - Magnetic - Universal Motors
... It can operate well on AC because the current in both the field and the armature (and hence the resultant magnetic fields) will alternate (reverse polarity) in synchronism ... run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron ... Transformer action induced current into the rotor ...

Famous quotes containing the word current:

    I don’t see America as a mainland, but as a sea, a big ocean. Sometimes a storm arises, a formidable current develops, and it seems it will engulf everything. Wait a moment, another current will appear and bring the first one to naught.
    Jacques Maritain (1882–1973)
