Text Appearing Before Image: ereis complete continuity of insulation throughout each phase of the winding.The star point is carefully spliced and vulcanized in a special mould. Inthis type of machine the free ends of each phase are brought out througha stuffing-box on the motor-frame for a length of about 50 feet, and thereterminate in a three-pole watertight coupling, to which reference willbe made again. The extended cables are protected by armoured rubberhose. The overhangs of the coils are clamped securely to the motor-body. The iron core-plates of both stator and rotor are treated with aspecial varnish, each plate being passed through a machine resemblinga domestic mangle, the rollers of which revolve in the liquid. By thismeans an even layer of varnish of mimimum thickness is applied to eachplate, thus effectively sealing the joints in the assembled core. (2) is therotor and shaft, and (8) the impeller already referred to. (3) and (4)are steel roller-bearings for the radial load, and are mounted in gunmetal Text Appearing After Image: Fig. 7.—Component Parts of MoTOR-puMr shown in Fig. 6. 1920-1921.] IIAMSAY SUBMERSIBJ.E ELECTRIC MOTORS. 173 housings (6) and -(T). (5) is a double-thrust ball-bearing, which locatesthe rotor axially and takes the thrust due to the pump. This bearingis mounted with one radial bearing in housing (7), and the whole iscarried in the motor end-bracket (10). The housing (6) is carried inthe volute casing (9), which forms the other end-bracket of the motor. The water-channel within the volute is of standard design, withgradually increasing sectional areas in the direction of rotaton of theimpeller. The boundary-line of the volute is such that it conforms to theactual angle of discharge of the water from the impeller. (11) is a filter-body attached to the discharge flange, and into the centre of this bodyis fitted a brass cylinder (12), the inside diameter of which is equal tothe diameter of the discharge-pipe. The function of this filter will be rrn Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work. -
