  • REPAIR METHOD OF STATOR IRON CORE
    Publication number: 20230027901
    Abstract: A repair method of a stator iron core which has a slot for accommodating a stator coil, and is formed by laminating silicon steel sheets. The method is implemented by moving a part of the silicon steel sheets which form the stator iron core while holding the stator coil in the slot to form a gap between the laminated silicon steel sheets of the stator iron core in the existence of a damaged part, and adding an insulation to the damaged part of the silicon steel sheet from the gap formed between the laminated silicon steel sheets to repair the damaged part of the silicon steel sheet.
