Abstract
The invention relates to a method for manufacturing the impeller of a centrifugal, that is, a radial compressor or radial blower, said impeller being mounted directly on the shaft of an electric motor. An essential feature of the invention is that the composite material impeller is made using an RTM process, wherein the RTM mold has a core and accurately trimmed fabrics placed therein in such a manner that the fabric layers, or preforms, are pulled onto the core thus achieving a maximally optimized use of materials in the structure.
