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 Small
wind generator. 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.
Problem with old style wind turbine
systems:Most old style wind turbines are heavy weight with unpredictable
reliability, hard to install and require lots of maintenance. Due to the fact
that most installations are in very remote and inaccessible locations, the old
style systems make regular maintenance costly and sometimes impractical.
Windmax Solution:Windmax H series maintenance free design has a minimum of
moving parts with inherent reliability. Our light weight, compact die-casting
aluminum alloy generator design makes installation very easy. Rotor blades
built with latest advanced thermoplastic engineering and precision injection
molding technology is durable and efficient.
WindMax H series components built with
advanced technologies Generator:
Generator: The generator is built using
high-performance rare earth neodymium permanent magnets, so the alternator is
compact and light weight with a high power generating efficiency. The 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.
The generator features class B insulation, IP55 class protection, and is
designed with a sufficient cushion of overload to ensure overall wind turbine
reliability.
Generator housing is made with precision cast
technology from high strength aluminum to assure a high quality finish. It is
designed for various working conditions such as severe climate, sand and salt
corrosive environments and marine usage. Aluminum die cast alloys can withstand
the highest operating temperatures of all die cast alloys. Ideal for demanding
environments, it offers high strength and rigidity along with good corrosion
resistance and heat dissipation.
Rotor blades:Patented Blade design vs.
traditional hand made fiber glass blades.
