Product Description


Product Information for wind turbine generator

50000W is a typical HUMMER smart Wind turbine, which with a series of high-end technologies and refined material, 50000W wind turbine is excellent in generation, stable in output and reliable in practice.

Efficient Generator

Hummer generator is one of the most advanced generators in the world. Made of refined permanent magnetic material, special copper alloy, aviation aluminum alloy and stainless steel, it is highly efficient in power. Due to its smallness, it is able to be placed inside the nose cone to reduce air resistance and increase efficiency.

Due to its advanced technologies, refined materials and unique design, 50000W wind generator's wind energy utilization factor is as high as 0.42, while generator efficiency is >0.92.

Smart Control

50000W wind turbine is controlled by a comprehensive smart system. Through our years of monitoring on wind turbine operation, we successfully develop an automatic control system for small and medium scaled wind turbines.

This smart system is able to automatically seek wind direction and constantly monitor: generator working status, rotation speed,generator temperature, wind speed and direction etc. All data will be transmitted to control center.

When abnormal situation takes place, our control center will instruct wind turbine to deflect from wind direction. After problem is released wind turbinewill turn to face the wind direction again and resume generation.

Company Information


Anhui Hummer Dynamo Co., Ltd. is a burgeoning professional manufacturer of wind generators with high-tech in the field of wind energy.

We specialize in the research, development, production and promotion of small and medium scaled wind power generator systems, and also provide solutions for setting up small-scaled wind farms. After nearly 30 years of development, we now own seven patented technologies and the small, highly efficient wind turbine system with independent intellectual property rights.

There are more than 200 employees in the company including 40 R&D staff. Apart from many testing and examining systems, there are more than 70 sets of large production equipment for processing, cutting and spray

painting. The monthly output of wind generator is 3,000 sets. Hummer produces both off gird and grid tied wind power generating systems from 400W to 100KW, a total of 23 specifications They are light, small, fast, stable and highly efficient.

Hummer wind turbines have obtained European CE certificates, the generator American UL certificate. Hummer wind turbines have been exported to 112 countries and areas, such as the USA, Australia, Germany, the UK, France, Russia, Brazil, South Africa, India, Israel, Japan, etc. With rich experiences in production, marketing and after-sale service.

Unlike other traditional wind turbines, Hummer's wind generator has the features of being "light, small and highly efficient". Subsidized by the state, the experts in Hummer provide a reliable force for product updates & technical supports. That is why Hummer is leading the way of wind generators production in China. The management team has abundant experiences in production, marketing, and services. Until now it has formed a complete management system for researching, studying, developing and services. Hummer aims to be one of the best wind turbine manufacturers and wind power providers in China as well as a worldwide influential enterprise.

Currently we offer wide range:
