Abstract
1467164 Making dynamo-electric machines SIEMENS AG 19 June 1974 [29 June 1973] 27290/74 Heading B3A A method of making a dynamo-electric machine comprises assembling a rotor 3, a wound stator core 1, and a housing together with a sealing sleeve 8 so as to define a casting mould, introducing a settable sealing composition, e.g. a casting resin 2, into the mould to seal the winding in position and removing the sleeve 8 through at least one opening 51 provided in the housing after the composition has set thereby defining a predetermined air gap between the stator core 1 and rotor 3. The sleeve 8 is inserted into the wound stator core 1 and end shields 5, 6 are secured to the core by rivets 20. The sleeve also serves to centre the rotor in the stator. A sieve-like foil 7 is placed in the shields 5, 6, prior to assembly on the stator core, the foil serving to shape the winding end turns and keep them a minimum distance away from the shields, which are conductive, for insulating purposes and to provide the heat dissipation required. Instead of foil, a fleece-like insert or plastics clips may be used or alternatively an insulating layer may be sintered on to the inner surface of the end shields. The sleeve may be helically wound and be removed by being pulled through an aperture in an end shield. The sleeve 8 may be formed of trapezoidal segments 81-88 which are disposed to provide lug-like projections 811-871. The projections are aligned with slots in the end shields 5, 6 and projects through them to allow for removal when the casting resin 2 has set. The sleeve may be removed by melting out. The end shields may have provision for accommodating radially disposed cooling tubes (13), Fig. 3 (not shown), or electric components (14), Fig. 4 (not shown). The end shields 5, 6 may also be provided with apertures (16), (17), Fig. 5 (not shown), into which the casting flows and on curing anchors the end shields against axial and rotary movement.
