Abstract

393,617. Motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 7, 1931, No. 33916. Convention date, Dec. 8, 1930. [Class 35.] Motors with unwound armatures; casings.- In a gramophone motor wherein the stator is surrounded by the rotor, each element is surrounded by a screen of magnetic material individually associated therewith to form a substantially complete enclosure. In the form shown, the rotor c is secured to the turntable d and has a magnetic screen e, whilst the housing b of the stator a also serves as a magnetic screen. Specification 379,065 is referred to.
