Abstract

234,821. Siemens - Schuckertwerke Ges. May 28, 1924, [Convention date]. Armatures, dampers and short-circuited screens on cores of. - In an electrical machine additional closed windings surrounding the slot leakage fluxes are provided for the purpose of preventing eddy currents in the conductors and for improving commutation. The damping windings comprise two closed coils c, k of low resistance, the portions outside the slots being bent back and if necessary, of greater cross section than the slot portions. Eddy currents within the damping coils themselves may be diminished by embedding them in iron, or by using subdivided conductors. The coils are arranged so that the upper part may be pulled out and bent to the side to allow the main winding v, w to be introduced into the slot.
