Abstract

221,811. British Thomson-Houston Co., Ltd., (Assignees of Freiburghouse, E. H.). Sept. 11, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Cores.-The solid or substantially unlaminated rotatable field member of an alternating-current machine is formed with circumferential grooves on its surface for lengthening the path of the induced eddy currents, and thereby reducing the pole-face losses. The grooves also increase the cooling surface.
