Cryogenic Aluminum Armature Bar for High Power Generators

Abstract

To improve the design of light-weight cryogenic alternator it is necessary to pay extreme attention not only to the design of the rotor, but to the stator design as well. Main elements of the stator are: the three-phase armature winding and the outer screen, which protects the alternator exterior from the magnetic flux, induced inside, and the alternator interior from the outside stray magnetic fields. The outer screen may be ferromagnetic or electromagnetic. With the increase of the number of poles the role of magnetic screen decreases, so in multi-pole alternators it is possible to exclude the outer screen at all.
