low rpm permanent magnet alternator electric generating windmills free energy motor for sale

Introduction

 

Richuan Horizontal Axis 360V 20kw wind turbine,Use 20KW Wind Generator System  to generate electricity which charge into storage battery group (off grid) or feed into the grid net (on grid). Through the multi-voltages power supply system, the 3 phase wind power voltage can be rectified into DC and convert to AC power used for home, commercial or other industry power supply application

 

Feature

 

•Excellent power output performance during the common wind speed between 5m/s and 9m/s

•Equipped with high quality NSK brand sealed bearing

•Cast steel body with anti-corrosion treatment for working well in harsh environment

•Direct drive, gearless, maintenance-free permanent magnet generator

•Multi-protection methods ensure system in high reliability and safety during high wind speed operation (mechanical yawing + electromagnetic brake + manual brake)

The permanent magnet generator

 

 

Blades:

 

FRP, (Fiber Reinforced Polymer) acronym, the existing CFRP, GFRP, AFRP, BFRP so on.

Chinese in FRP refers GFRP. FRP composite material is a fiber material of the base material

according to a certain mixing ratio, after a special extrusion die, drawing the formation of

high-performance materials.Since the resin used in different varieties, so there are glass fiber

reinforced polyester, glass fiber reinforced epoxy , phenolic FRP said. Light and hard,

non-conductive, high mechanical strength, recycling less resistant to corrosion.

 

 

The inverter:

 

1.digital design, simple structure, powerful, stable and reliable

2.using annular isolation no-load loss of transformer, inverter with high efficiency

3.pure sine wave, automatic voltage regulator, output and frequency, waveform distortion rate ≤ 5%

4.strong overload capacity, 120% overload can work normally for 1 minutes; 150% overload can

   work normally for 10 seconds

5.high reliability; high stability; high shock resistance; low noise, noise≤ 40dB

6.input / output circuit complete isolation design, improve product stability

7.has over-voltage, under-voltage, overload, overheating, short circuit, lightning protection function

 

   and alarm function

 

  Tower:

 

Tower bar is 6 meters high
