Abstract
1501371 Making electromagnetic windings; composite castings SBW ENGS Ltd 30 Jan 1975 [30 Oct 1973] 50348/73 Headings B3A and B3F [Also in Division H2] A double-layer electrical winding, e.g. for an A.C. or D.C. motor or generator, or a D.C. electromagnet is made by forming a core from two sets of laminations each having apertures so as to form two layers of slots in the core, filling the slots with conductive material to form the windings, and connecting the conductors of one layer with those of the other layer by end windings cast in situ. Fig. 1 shows the central part of a core assembled from inner laminations 11 with apertures 15 and outer laminations 12 with apertures 16. Central apertures 13 are provided for a shaft. The apertures are aligned by using notches 17, 18. Inner and outer laminations are separated by a layer 14 of alumina, and individual laminations are also preferably insulated from each other. When correctly assembled, the laminations are bonded together or otherwise held fixed. End sections 20, Fig. 2, are assembled so as to form skewed conductor slot portions, and the central sections may also be non-linear, depending on the type of winding desired. If there is not need to pass magnetic flux in the end sections 20, their apertures may be of larger size than those in the central portion. Apertures 15, 16 are preferably about equal in cross-section, and may be elliptical. The inner surfaces of the slots formed in the core are then coated with insulation, and aluminium is cast into the moulds to form windings, by centrifugal casting, gravity die casting, pressure die casting, or pore-free die casting, the latter involving filling the moulds with oxygen prior to casting. End connections 19 are cast at the same time using removable moulds, and may act also as cooling fins. The connections 19 at one end, or part of the peripheral surface at one end of the core, may be machined to form a commutator, or a commutator may be attached to the end connections 19 by pressure or electron beam welding, or to a machined end portion of the core. The whole of the outer surface of the core may be machined to expose the windings, in which case the apertures 16 have inward projections to retain the windings. In modifications, the end sections are formed from refractory material and the windings may be formed by forcing copper conductors through the slots.
