Three-phase alternator

asynchronous4-polefor wind turbine

750kW，800kW Asynchronous Wind-driven Generator Main technical features Reliability It applies nodular cast iron base and end cap with radiating rib structure， good low temperature property and mechanical strength. Due to nodular cast iron has good nature and structural design， motor structure enjoys high mechanical strength， excellent rigidity and vibration resistance. Reliable bearing design: Double ball bearing structure is applied by this motor and installation of which can be inclined. It employs poor-adhesive-contented insulation system，H grade insulation structure， and manufacture process of VPI integrated impregnation varnish. 　Main insulation and inter-turn of conductors have high shock-resistance voltage strength. Reasonable structural design makes the axle voltage almost as zero. Copper bar welded rotor is applied to ensure reliable operation of motor. Three coatings on the surface of motor enjoy excellent anticorrosion property， which ensures motor adaptable to various bad environments (Such as: salt frog， dust， sand and etc.). Convenience Four lead outlets can be installed at ventilation channel of motor base， which is easy for leads. Protection grade of junction box is IP54 design， and interior is equipped with earthing equipment. Front and back ends of motor are equipped with bearing non-stop oil filling and discharge equipments， easy for maintenance. It has oil drain pipe to storage waste oil.
