Comparison of Hybrid Wind Generators with Aerodynamic Braking and Electromagnetic Braking vs. Old Style Wind Generators with Mechanical Furling Overall High performance, high efficiency high reliability and superior workmanship, designed to work from low to high wind speeds Average efficiency, average reliability and average workmanship with deceiving rated output, designed for perfect wind conditions at rated wind speed, much lower output at realistic wind conditions, lower output at low wind speed, stop working at high wind speed. Wind/Solar Input Can be used as either wind turbine only or wind/solar hybrid system. Integrated wind and solar power sources to 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. Work with wind only, NO electricity generation when wind speed is too low Design Highly reliable, Innovative two moving part design with 25-year maintenance-free generator life span  Average efficiency, less reliable three moving part design, furling components wear out quickly and require a lot of maintenance. This would lead to possible mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other possible negative results in the long run. Braking & Efficiency High efficiency: Abandoned the traditional failure-prone mechanical furling system and solved efficiency, safety and reliability problems facing most small wind turbines. Advanced speed limitation is achieved through electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending turbine’s operating speed range into higher speed winds and lower speed winds which are missed by the old style wind turbines.  Average efficiency: Braking depends on unreliable, problematic mechnical furling which only 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. The furling system kicks in either too early or too late to go back to normal operation. This results in average efficiency. Performance at low wind speed Strong Neodymium magnet PMA, the unique winding and multi pole design reduces the start-up torque of the alternator that assures the it can generate more electricity at low wind speed than other systems.

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, patent pending 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. Easy-to-install, light weight, compact, reliable and maintenance-free wind turbines, designed for both land-based and marine applications.
