AERO2GEN 50WWind Generator

The Aero2Gen wind turbine was designed to charge 12 or 24 volt lead acid and nickel cadmium (NiCad) batteries. Designed for optimum wind speeds between 8 and 15mph, the Aero2Gen is a reliable light to medium duty generator for relatively low wind speed sites.

The Aero2Gen's high efficiency brushless alternator incorporates heavy duty stator windings and high energy permanent magnet rotors. Corrosion-resistan marine grade materials are used throughout construction.

patented design EP 1 489 427, DE 103 27 632, EP 1 398 637


The wind transmitter is designed for the acquisition of the horizontal component of the wind speed in the fields of meteorology and environmental measuring technology. The measuring value is available at the outputs in digital form It can be transmitted to display instruments, recording instruments, dataloggers, as well as to process control systems. For winter operation the instrument is equipped with an electronically regulated heating, which guarantees a smooth running of the ball bearings, and prevents the shaft and slot from icing-up.

2. Construction and Mode of Operation

A low-inertia cup star with 3 cups, made of carbon-fibre-reinforced plastic, is set into rotation by the wind. The rotation is scanned opto-electronically, and is converted into a square wave signal. The frequency of this signal is proportional to the number or rotations. Depending on the supply voltage, the output signal ranges between maximal output voltage and ground or a potential (life-zero), lifted by approx. 1,2 V. The supply of the electronics can be done by DC-voltage of 3,3 V up to 42 V at a very low current consumption. An AC- or DC-voltage of 24 V is intended for the separate supply of the optional heating. In all probability, the heating guarantees a trouble-free function of the Wind Transmitter First Class even under extreme meteorological icing-conditions.

The outer parts of the instrument are made of corrosion-resistant anodised aluminium. Highly effective labyrinth gaskets and O-rings protect the sensitive parts inside the instrument against humidity and dust. The instrument is mounted onto a mast tube; the electrical plug-connection is located in the transmitter shaft.
