Abstract
A filler-impregnatable device for a large electric machine, such as a stator or a rotor, includes a carrier body having slots formed therein defining slot walls. Conductor windings have conductor devices disposed in the slots associated therewith. Impregnatable insulating layers each surround a respective one of the conductor devices. Impregnatable first semiconductor layers each envelope a respective one of the insulating layers. At least one impregnatable second semiconductor layer is disposed between the first semiconductor layer of each respective conductor device and at least one of the slot walls of the associated slot. The at least one second semiconductor layer is electrically connected to the first semiconductor layer of each respective conductor device. Filler-permeable separating layers are each disposed between the first semiconductor layer and the at least one second semiconductor layer of each respective conductor device. The separating layers reduce but do not prevent adhesion of the first semiconductor layers to the second semiconductor layers to be provided by a filler.
