Shading coils for alternating current electromagnets
Briney, Gerald S
MetadataShow full item record
In general, contrary to popular opinion. heavy shading coils are not as effective in reducing noise in an alternating current electromagnet as those which are smaller and thus have a greater value of resistance. This occurs because in addition to obtaining the greatest shift possible between flux produced by the unshaded and shaded portions of the pole the magnitudes of these fluxes should be equal.
