Abstract

1351769 Moulding stator housings GENERAL ELECTRIC CO 19 April 1971 [29 Jan 1970] 20135/71 Heading B5A [Also in Division H2] A housing formed about the stator of a dynamoelectric machine comprises an electrically insulating inert inorganic particulate material bonded together by an adhesive material to form an impact-resistant thermally conductive rigid mass. Many examples of the respective materials, such as sand, mineral ores, chalk, mica, or a two part thermosetting resin, are described in the Specification. As shown in Figs. 5 and 6, it is formed by depositing a metered predetermined quantity of sand 78 into a mould 64 whilst the latter is vibrated by horizontal and vertical vibrators 80a, 80b, and then at a filling station admitting a metered predetermined quantity of the adhesive material 89. The gravity feed may be supplemented by air pressure via a regulator 91, and the resin is then cured. In another embodiment, Fig. 9, sand 138 and adhesive material 137 are discharged concurrently or sequentially into a mould 121 that is rotated by a motor 127 and across which a blower 139 directs hot air.
