The Difference Between Stator and Rotor Linquip

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.
