Abstract
1,150,975. Retaining windings in electrical machine core slots. LLOYD DYNAMOWERKE G.m.b.H. 27 Oct., 1967 [15 Nov., 1966], No. 48933/67. Heading H2A. A dynamo-electric machine has a winding 19 secured in each of a plurality of open slots 10 by two closure members 21, 22, each of L- shaped cross-section with an oppositely extending arm 25, 26 at the top of its stem, such members being so fitted against each slot side wall that their inner arms 23, 24 are seated in grooves 16, 15 in respective walls and their outer arms 25, 26 project across the gap towards each other at the slot opening so as to partially close the slot, and a packing means 27 is located between the winding outer surface and the inner arm's inner surface. The closure members may be of ferromagnetic material and the packing means of non-magnetic material ; in Fig. 3 such means is a hollow body through which cooling air is impelled from the ends to the slot opening. In a synchronous machine rotor the means 37 may be electrically conductive to form a rod of a damper type, or of different magnetic permeabilities to provide a special field curve form.
