Superwind Wind Generators - Technology

Superwind Technology

In the past small wind generators were used rarely for professional applications, since they generally did not have effective safety systems and since they were not reliable enough for automatic and unattended operation.

Superwind generators define the new standard for micro wind turbine technology. They fulfill highest professional requirements and can be operated completely unsupervised even under extreme climatic conditions.
Due to their sophisticated technological concept and their aerodynamic rotor control system superwind generators guarantee maximum reliability and durability and are second to none when it comes to reliable power supply.

Superwind Rotor

The basic innovation of superwind is its novel aerodynamic rotor control system. Similarly to large wind turbines it adjusts the pitch angle of the rotor blades. The mechanical controller is fully integrated into the hub and works without expensive electrical or hydraulic components. Instead, the controller is actuated by forces arising at operation of the wind turbine itself. The forces are effected by the geometric and kinematic lay-out of the rotor and controller mechanism.

Superwind Rotors

The control system responds very quickly, and precisely controls the power produced and the rotor speed. The customer benefits are:

Outstanding reliability under all operation conditions
Fail-safe: even at electric system brakedown no dangerous rotor overspeed.
Low loads for high durability.
Automatic and unattended operation (with charge regulator)
Minimum noise emission since the rotor blades are feathering to leeward and and noisy stall effects are excluded.
The rotor blades were developed using modern computerized calculation and simulation methods. The airfoils had been wind tunnel tested and were specifically developed for a small size wind turbine.

Superwind Generator

The generator is a brushless synchronous generator with permanent magnet excitation. The three-phase alternating current is rectified by an internal rectifier. The generator is especially adapted to the aerodynamic power characteristics of the rotor.

Superwind GeneratorsSuperwind Generators

High-grade Neodymium magnets are used for optimum efficiency. All electrical components are properly dimensioned for high surge currents, low thermal loads and high durability. The aluminium generator housing provides perfect heat dissipation. The generator shaft bearings are stainless steel bearings, lifetime lubricated and sealed against humidity and dust by low friction seals.

Superwind YawingSuperwind Yawing

Yawing is effected by a wind vane and yaw bearings. The yawing system is designed for operation even on turbulent sites and also works perfectly on yachts, no matter whether reaching or sailing downwind. For power transmission between the fixed and the pivoting part, the wind generator is equipped with sliprings and carbon brushes.

Superwind Materials

Superwind generators are entirely made of high grade and corrosion-proof materials. All mechanical components are integrated into sealed housings and are effectively protected against dust, salt and humidity. The housings and the wind vane are made of sea water-proof aluminium alloy with additional powder coating. All steel parts like shafts, axles, bearings, bolts and nuts are made of stainless chromium steel. The rotorblades are made of carbon fiber reinforced plastics.
