Abstract

1395742 Making stators SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 16 May 1972 [18 May 1971 24 April 1972] 22981/72 Heading B3A [Also in Division H2] A method of manufacturing the stator of a rotary electric machine, e.g. a motor, comprises locating a plurality of preformed separate stator teeth, e.g. 1 in Fig. 1 around the periphery of a cylindrical support such that axially open ended and radially outwardly open slots 4 are provided between the teeth, inserting stator windings 3 into the slots, closing the radial openings of the slots by a magnetic yoke 2 and simultaneously or subsequently so applying a lacquer or curable moulding compound 5 that the teeth and windings are joined together to form a rigid assembly. As shown in Fig. 1 the yoke 2 comprises annular laminations, but in other embodiments it comprises a plurality of trapezoidal elements (11), Fig. 2 bridging adjacent teeth (10), or is of moulded magnetic plastics material (81), Fig. 12, which may have a fastening structure (83). The support may be a sleeve (18), Fig. 2 or a removable mandrel (55, 56), Fig. 14, and during the moulding process or by the sleeve (16) these are formed aligning and abutment surfaces 6, 7. by which a rotor may be supported. The teeth are of grain oriented material, and their pole tips are flared outwardly, (Fig. 3), to provide a minimum spacing (30) therebetween. To reduce burrs the teeth may be heat treated before assembly.
