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.{{Cite web|url=http://www.stator-systems.com/index.php?Itemid=63&category_id=1&option=com_virtuemart&page=shop.browse.|title = Slot insulation machines}} This shielding material separates the rotor's electrically conductive winding from its body.Payne, B.

Temperature ratings
Due to their operating environment, slot insulation must be capable of withstanding high temperatures. In the 1970s, slot insulation materials often had a Class F temperature rating (an operational range up to 155 °C).Gibney, J.
