Design Features

Advanced over-speed control mechanism vs. old style furling

Problems with old style furling:

Old style furling works well in an ideal, wind tunnel test environment. Realistically, wind speed and wind direction changes frequently and mechanical furling doesn’t have instantaneous response to actual changes of wind status. Especially in bad weather conditions, small wind turbine furling components wear out quickly, therefore, increases maintenance costs and shorten wind turbine service life or causes system failure.

Most of old style furling based wind turbines have three moving parts. It is the moving parts for mechanical over-speed protection that wear out and require a lot of maintenance. Operation of furling based wind turbines would lead to mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other devastating results in the long run.

The rule of thumb for a reliable wind turbine is that the fewer the moving parts, the more reliable the wind turbine is.

Windmax Solution:

Windmax H series adopted Innovative over-speed control so it improves the reliability by abandoning the moving parts for mechanical over-speed protection and minimizing the moving parts to only two.

Innovative over-speed control design of the Windmax H series:

Windmax H series speed limitation abandoned the traditional failure-prone mechanical furling system and solved safety and reliability problems facing most small wind turbines. Advanced speed limitation of Windmax H series is achieved through advanced electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Electromagnetic braking is used in combination with Aerodynamic braking to reduce the rotational speed of the generator.

Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending Windmax H series turbine’s operating speed range into higher speed winds and lower speed winds which are missed by the old style wind turbines.

1. Electromagnetic speed limitation:

Controller will monitor the wind generator rotation through the wind generator output voltage and frequency, and will timely control wind generator rotation by generating reverse reluctance torque if necessary, according to different wind conditions and battery status. Electromagnetic control features quick response, high reliability and therefore ensures the entire control system to be highly reliable.

2. Blade aerodynamic braking:

In high wind speed conditions, patented blades will generate a reverse reluctance torque, so that the blade efficiency falls and the blade rotation speed starts to decline. With the continuing reluctance torque, blade rotation speed is limited to a certain range to prevent damage to the wind turbine blades.

Higher performance at low wind speed Problem with small wind turbine system on the market today The most challenging problem facing small wind turbine systems is that power output is very low or close to nothing under low wind condition. The wind speed in most locations don’t stay at rated wind speed all the time, wind turbine actually operates at wind speed lower than rated wind speed at most of the time. In order to have good overall energy output, it is critical for small wind turbine to output as much as power at low wind speed. WindMax Solution: Strong Neodymium magnet PMA, unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. WindMax system components such as wind generator and blades are designed to output more electricity at low wind speed than other small wind turbines on the market today. WindMax system’s excellent power output under low wind speed results in greater energy production yield and lowest ownership cost.

Wind-solar hybrid power generation wind turbine system

Problem with single source renewable energy system:

1st Generation single source renewable energy systems such as solar systems or wind turbines don’t use renewable energy efficiently. Wind turbines creates less output during the summer, whereas during the winter the solar panels will produce less output.

Windmax Solution:

Our Windmax hybrid solar-wind turbine integrated wind and solar power sources capture the most energy in all conditions. Since solar and wind energy availability differs by locations, seasons and climates, solar and wind energy can be mutually complementary in that solar and wind hybrid systems make full use of wind and solar energy together to generate as much power as possible compared to a single energy source for power generation. A solar & wind hybrid system is more cost-efficient than wind or solar alone.

The Advantages of Vertical Axis Wind Turbines



One mistake we make is not watching for new designs in old technology. New designs are made because old ones have become unacceptable. When we hear or see a cover story on a topic we think we know a whole lot about, we flip the page or go on to the next topic. Many people who think they know a lot about them tend to skip all the news about wind turbines because they know so much about the old systems they are board with the topic. Really all they truly know about is the OLD wind turbine technology.

Things are very different now and unlike many other power generators, wind power is user friendly. New designs in axis wind turbines for homes are driving the winds of change for home owners and energy efficiency. The most successful green power systems of the present day and the future is and will be supplemented by wind power generators. Read on to find out why and what new designs are irrefutably “The Next Big Thing” for going green.

The current movement in green energy is obvious when you watch the evening news but one thing you rarely see is the use of wind power at home. Maybe they want to keep this one a secret and I know why. Energy generated by the wind is currently the only true green power generation source by all standards of measurement. The reason being that you can build a wind turbine out of basic materials like scrap wire and metal parts with very few tools and virtually no technology gadgets. If a wind turbine breaks down, repairing it can be done with very basic materials and low-tech or should I say no-tech pieces and parts.

You can’t even dream of doing that with gas motor generators and definitely not solar cell power generation because the many technologically complicated parts require factory made replacements rather than just repairs. In the recent past you could understand why people with lots of common sense would reject the idea of electrical power generation by wind due to one little big batch of problems.., weather proofing the delicate construction of the bearings and electrical system along with a low power output due to very week magnets in the motor and then mounting all that atop a large pole with guy wires etc…I’m sure you get the picture.

All of those problems have been solved with the development of super strong Neodymium motor magnets and a completely new evolution of blade systems to quietly catch the wind in lower elevations (on rooftops) and completely new style of no friction magnetic levitation bearings and as of late we have some brand new artistic designs for the Vertical Axis Wind Turbines STYLES. That’s right, if you don’t like the thought of big noisy visually obstructive wind turbines, you must take a look at the new low profile, high output, easy install axis wind turbines. Most people use the words “Easy Install” as a sales tactic but the truth is simply that if its hard to install, it will cost more.

It is up to us to keep the bottom line low which makes the bottom line more in tune with the green power movement. I hope this helps and if want to see much more on this and many other turbine topics click on the links below.

Understanding How Wind Turbines Generate Power



Wind power is considered a renewable energy source because it will be with us as long as the sun beats down on the planet. Wind is a creation of heat produced by objects warming up under the relentless rays of the sun. Certain objects warm up faster than others. When this occurs, wind is created. As hot air rises off the hotter objects, cooler air rushes in to fill the gap. This rushing process is, of course, wind.

Wind power has long been of interest to scientists and energy companies. It is relatively cheap and can easily be tied into the current utility grids that feed power to nations. The question with wind power has always been how to generate enough energy from wind power to make it feasible. The entire discussion comes down to wind turbines.

Wind turbines are the devices that catch the wind and convert the inherent energy into electricity. The process works exactly like a hydropower dam. As the wind hits the turbines, the blades catch it and spin. The spinning motion then cranks a turbine, which kicks out electricity. The only difference between the two processes is we are talking about wind instead of water.

A single hydropower dam can produce a lot of electricity, but a single wind turbine cannot. Why? Well, the water rushing through a dam is condensed under the weight of itself. When it is released into the generator shutes, it also runs at a near vertical angle to maximize the speed of the water and generator cranking output. With wind, both of these factors are non-existent. One cannot really harness the wind to really power up a wind turbine. Instead, one has to install dozens and even hundreds of turbines to generate significant amounts of electricity. As you might imagine, this can cause problems.

The biggest problem with wind power is the number of turbines needed to produce enough electricity. While the turbines have grown more efficient and larger, one still needs significant numbers to produce enough tangible energy. The two primary solutions are old and new. The old solution is to find great swaths of vacant land for the turbines. With growing populations, this is still relatively difficult and expensive. The new solution is to build wind farms at sea. This makes much more sense since the wind on the ocean is nearly constantly there and the “land” isn’t costly.

At the end of the day, experts estimate wind power will account for upwards of 20 percent of all our energy needs in the next two decades. With further refinements and the use of offshore platforms, the number could be much higher.
