Cast Coil GmbH

Cast Coils the smart way to design better electric drives! A wide range of requirements are placed on the windings of electrical machines. On the one hand, the maximum performance of the electrical machine should be achieved by a high slot fill factor and thus the best possible utilization of the available installation space. On the other hand, the best possible cooling of the conductors must be ensured and the occurrence of additional losses due to current displacement must be avoided. There is an overarching desire for cost-effective and automatable production and assembly of the coils. We developed a process which allows coils for electrical machines to be manufactured by casting. The coil geometries with flat conductor arrangement which can be manufactured using this process offer decisive advantages over conventionally manufactured windings. The casting production can be carried out either by die casting, low-pressure casting or investment casting and the coils can be cast from copper as well as aluminum.
