Permanent magnet synchronous generator have characteristics of ultra-low starting torque, high efficiency, The electricity generating performance at low speed, smooth operation, compact structure, small volume, light weight, easy to install, and maintenance etc^
The exerted shaft of products is the tapered with hex nuts and locknut; Use extruded aluminum body, stainless steel front and back covers, stainless steel coverCompletely sealed bearings for long life and corrosion resistance and heat dissipation
With fractional slot winding, products is reducing the starting resistance moment that lower than the national standard for 40%~50%.
Rotor and stator with high quality cold rolled silicon steel is high strength, , difficult deformation; Stator winding choose H class composite coating paint baoyuan copper wire around system by the constant temperature and vacuum heat for combination immersion paint, that improve the class of insulation; Magnet steel choose high performance 40 SH NdFeB magnets rare earth permanent magnet materials; The rotor magnets fixed for enchase type, super glue adhesive, epoxy resin packaging technology, improve the stability of the magnet steel, corrosion resistance. Similar products reduce more than 10% material consumption.
This generator can be used for residential wind turbine system and others. It can be used for Horizontal wind turbine and vertical wind turbine, Some friend even used it for water generators. It is very effective for this system. At the same time, it is very easy to installation.
