The stator winding of the motor adopts the advanced less glue system, which greatly improves the life and reliability of the insulation system, and the insulation life is up to 60 years. The generator adopts a solid and reliable structure design, which can meet the requirements of safe starting and operation under earthquake conditions. With the advanced design of radial axial mixed air path and oil cooling system, the temperature rise of the whole machine is reduced, the structure is simple and reliable, and the system reliability is improved.
