Home wind turbine alternator (vertical or horizontal axis)
Brushless roto-statoric unit with permanents magnets for electric current generation with low rotation speed.At this period of use of renewable energy, alternators are a very good alternative with excellent ratio (investment)/(Current produced quantity). Excellent efficiency at any wind speed make them an essential element. Allytech permanent magnets alternators, as a kit or ready to use, allow the owner of wind turbines to make their own energy. Thoses rotostatoric installation equippe low and medium power wind turbine with vertical or horizontal axis.
Allytech offers different configurations for his alternators:
As a kit to fit and adapt to third party system, with or without specific tools.
Ready to use, built-in with guidance and output shaft to fix to the existing shaft.
Alternatively with a speed increaser (if the wheel rotation is slow)
Complete generating set, ready to fix on wheel shaft end.
Equipped with rectifier, inverter and batteries (for connecting to the electrical grid)
Why to equipped water mill with ALLYTECH generator?
For isolated or grouped inhabitation, wind bring the power wich will be transform into electrical power. If the wind is irregular, the alternator produce a current with variable frequency and voltage, depending on the rotation speed. In this case is it possible to heat a water tank. To have a stabilized tension at 400V/50Hz (EDF standard) Allytech suggest a rectifier and inverter, eventually with batteries.
Large range of winding and dimensions give the best speed / power / size ratio, to generate your own electricity.
The rotation speed of small wind turbine, especially with vertical axis, is low (20 to 100 rpm). Fortunately, Allytech alternators produce a high power even at low rotation speed. A speed increaser is often recommended . And in case where it's necessary slackening of the effiency remain minima.
Allytech permanent magnets generators advantages
Low rapport or absence of speed increaser
High massic power in direct driven applications
Optimum efficiency on the near whole speed range
Possible rotation speed variation
Simplified mechanical conception
Easy mechanical interfacing
If the installation is made with electronic cabinet, the optimisation settings can be adjusted A POSTERIORI.
