ABSTRACT:
The present invention improves the heat resistance and strength of insulation material inserted between a core and a coil of an electrical machine. A slot liner is placed between a core of an electric motor of an electric machine and a conductor of a coil. The slot liner has a multi-layer construction with an aggregate mica insulation sheet, which has excellent mechanical strength, and a peeled mica insulation sheet, which has excellent voltage resistance at high temperatures. The slot liner can include a main insulation sheet and a reinforcement sheet. The reinforcement sheet is placed between the main insulation sheet and the core at the ends of the slot.
