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.

A lot of hype has been going around the gas turbine powered engines found on high-end RC toy jets. These new breed of RC toys promise to dominate the skies in the coming years since the interest on these latest radio controlled aircraft seem to be gaining ground. This is despite the fact that these particular types of toys also seemed poised to cause a huge dent in everyone’s wallet. It appears now that RC enthusiasts and hobbyists cannot seem to get enough of the new gas turbine powered engines on toy jets. So what is really all the excitement about? How do these gas turbine engines on RC toy jets work anyway?

For several decades, men have been fascinated by RC toy planes and helicopters. They love to watch it lift off the ground, play tricks in the air, and perform a perfect landing. Most of RC toy planes in the past are propeller driven because they are seen to be the most practical approach to make the plane fly. So it would be not surprising back then if you see a scaled down model of a jet fighter with a propeller on its nose tip. This went on for a long time until July 30, 1988, the first flight of an toy jet running on micro-turbojet engines was made with considerable success. From then on, micro-turbojets underwent a series of evolutions and finally, the modern gas turbine engines, which are being mounted on RC toy jets that you now see, emerged.

Gas turbine engines on RC toy jets work in a manner similar to that of real jet turbine engines. There are three divisions on the gas turbine engines and these are the compressor, the combustion chamber, and the turbine. The compressor is responsible for sucking incoming air and compressing them inside the cylindrical shroud. Extreme compression results in the heating up of air which then makes its way down into the combustion chamber where a fine spray of fuel, along with a glow plug, will be introduced in the area.

Just as expected, the fuel, mixed with hot compressed air and lit by a glow plug, will explode, forcing the exhaust gases out through the turbine and the small nozzle found at the rear of the jet turbine. This chain reaction produces the enormous thrust that enables the RC toy jet to take off and fly. Since the turbine and the compressor are linked by a common shaft, the expelled gas which turns the turbine is also the one that drives the compressor. This is why the gas turbines must be powered at the outset by an external source until the air inside the combustion chamber is sufficient and adequately heated.

So you see, gas turbine engines on RC toy jets work just like their real and full scale counterparts. It might just differ in size but the principle on how they work is basically the same.

A hybrid solar wind turbine generator is a reliable alternative energy source. It uses solar energy combined with wind energy to create a stand-alone energy source that is both dependable and consistent. Solar power and wind power are the two most available sources of power on the planet. Both are renewable energy sources that are plentiful all year round in all areas.

While solar power or wind power alone can fluctuate, when used together they provide a reliable source of energy. In many areas when the sun is strongest the wind speed is low and when the wind speed is highest the sun is often the weakest as in winter. The perfect solution is to combine these two forms of energy sources to create a constant energy flow. This hybrid system balances out the fluctuations in power to give a more even flow.

The hybrid solar wind turbine generator uses solar panels that collect light and convert it to energy along with wind turbines that collect energy from the wind. Solar wind charge controllers regulate the charging of the energy before it is stored in the battery banks. An inverter, located in the battery bank, changes the current from DC to AC. AC, or alternating current, is the type of power used in most homes and businesses.

The hybrid solar wind turbine generator provides low cost power. The power is reliable because it combines solar and wind power together. The operating costs are low compared with non-renewable sources. The use of the two sources – solar and wind – together help to give a stable energy supply to the batteries. When using exclusively one of the sources alone the batteries can become undercharged, when the source doesn’t produce enough energy to maintain the battery charge.
