Stator insulation
Slot insulation is the common name for shielding material used for the rotor inside a power generator. The slot insulation process for electric motors provides a barrier between the copper wirings and the steel lamination for all stator, armature and rotor products. This shielding material separates the rotor's electrically conductive winding from its body. WebEspecially for Hairpin or I-Pin stators, the welded zones of the stator have to be protected from the external conditions in order to achieve electrical insulation. There are different methods on the market ranging from powder coating, to …

WebThe electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by … WebGenerator stator-bar insulation systems have experienced a steady evolution since the beginning of central powerplants in the early 1900s. Initially, 1900-1915, natural products were used—for example, shellac, mica flake, paper. These materials apparently worked well on small, low-duty units, but were inadequate beyond perhaps 10 or 15 MW.
