To make the operation of wind turbines profitable day a company has Gaspe decide to push either side of the gigantic blades research but rather on the side of an unknown room, the alternator. The operation of a wind turbine is relatively simple. The wind turns the three blades, which constitute the rotor. This turns the alternator, which converts the energy into electricity.
This firm of Gaspe, Eocycle Technologies, specializes in the manufacture of alternators for small wind turbines, with a capacity of 5 kW for three years. In fact, the originality of the generator lies in the absence of gear box. This, because it has many moving parts that rotate in oil and then must undergo regular maintenance, is often the source of problems that require the stop of the wind turbine. The blades of a wind turbine rotate at speeds ranging from a 20 250 rotations per minute (RPM) according to the power. Since conventional generators must turn has a much high speed of to produce electricity, the use of a gear box to adjust the blade speed to that of the alternator is required. Eocycle rather uses powerful magnets that allow to obtain, in reduced dimensions, an alternator which can supply, we are assured, so much power at low speed. If this type of detour allowed to reduce the bill, the cost of returns from wind power become increasingly competitive.
