Abstract:
A nozzle for injecting a semiconductive coating material from the internal diameter side of a stator to the external diameter side of the stator is inserted in a core duct serving as an air flow passage between adjacent slots, and the semiconductive coating material is coated on the surface of the stator coil exposed to the air flow passage without drawing out the stator coil from the slot in the stator core to form a semiconductive coating layer, thereby repairing exfoliation of the semiconductive coating material on the surface of the stator coil.
