Model Number: ZH3KW-D-#1129 Brand Name: ZONHAN Key Specifications/Special Features: Structure and main performanceZONHAN turbines are made of strong cast steel that makes them durableWe can withstand harsh environments like strong winds and cold weatherUsing high performance NdFeB permanent magnet, the alternator is high efficiency and compactThe unique electro-magnet design makes the bonding force and cut-in speed very lowKey features:
  • The main generator shaft is machined from 40Cr steel and heat treated to make it extremely tough
  • The main generator shaft is tapered and has a key way where the blade hub mounts prevents any hub slip
  • High quality stainless steel bolts throughout the turbine, high quality castellated, stainless steel nut and pin secures the hub to the main shaft
  • High quality sealed bearings on the main shaft and the yaw bearing
  • Vacuum pressure impregnated coil winding in the generator
  • High quality neodymium iron boron material (NdFeB) magnets are used in the generator, these are also galvanized for longevity and are rated over 150 degrees Celsius
  • Our slip rings use J164 carbon brush which contains 90% copper, unlike most who use only 20% copper
