30KW PMGs for Vertical Wind Turbines

Main Feature:

1. 30kw PM generator at different rated PRM for verticall wind turbines.

2. The PM generators adopt optimum pole slot configuration, and shortened magnet circuit and the pitch of stator winding, material consumption reduced by 15%, so smaller and lighter.

3. The start torque is lowered by 40%, and the overall efficiency increased by 10%.

4. The speed of voltage buildup is lower with better performance in gentle breeze.

5. High grade cold rolling silicon sheet is used for the stator and rotor; the stator windings are wound with 180 grade combing paint coat series enamel-cover round copper wire, impregnated by the techniques of combing process of vacuum constant temperature and constant heat, higher insulation grade.

6. High quality 40SH,42SH,40UH rare-earth NdFeB(Neodymium Iron Boron) Magnet are used, and inlaid process for the fastness of magnet steel of rotor, strong adhesives splicing , epoxy resin encapsulating technology.

7. Adopt fully-enclosed NSK,NTN,SKF,C&U bearings and nickel plated 40Cr steel shaft with quenching and tempering treatment, and the outer frame is Zinc plated with anti-corrosion treatment.
