Definitions

  • the invention relates to a method for litting and winding coils on pole-armatures or field magnets for electrical machines, wherein the pole pieces are formed integral with the i core and, in order to obtain a field with a larger cross-section, are made to extend back to approximately the centre of same and over the coils, i. e. the pole pieces are cut away on the inside to accommodate the coils.
  • le Armatures or field magnets of this kind are used especially for small motors where it is essential for the cost of manufacture to be kept down to a minimum. Hitherto it has only been possible to fit these coils on armatures with cut-away pole pieces, by having one head of the core made removable. This involves an appreciable increase in cost and a more complicated design, which is particularly troublesome where the iron core coni sists of sheet ironlayers, such as dynamo sheets.
  • the bobbin When the first coil is finished, the bobbin, the two parts of which are now held together by the winding, is pushed laterally into its final position against the inner face of the pole piece, and the two halves of the second bobbin are then placed in position on the core and wound in a similar M manner. 'Vhen the second coil is finished,

  • Figure 2 illustrates the winding of the first bobbin.
  • J A Figure 3 the winding ofthe second bobbin, and 1 Y l 1 f Figure 4 one half of a bobbin in perspective.
  • l l
  • the armature or field magnet consists of the pole pieces 1 and 2 formed integrally with ancore 3 and the tips of the pole pieces extend backwards towards the centre so that the diS- tance aibetween the ends b of the pole pieces is somewhat greater than the width c of the bobbins l and 5, so that the latter, made up of two parts, can be placed on the core 3.
  • An armature for an electric machine comprising oppositcly disposed pole pieces and a straight core formed integral therewith the tips of the pole pieces being extended 35, backwards towards the centre of the core, a two-part coil Wound bobbin arranged on said core adjacent each pole piece and detachable means secured to the core for retaining said bobbins in their respective positions.
