Direct Drive - Half the Weight - Lowest COE

Introducing Boulder Wind Power's breakthrough axial gap, air core, permanent magnet direct drive generator. The BWP technology can produce the same torque with less than half the mass (Nm/kg) of comparably rated iron-core direct drive generators. Our proprietary air-core stator contains no ferromagnetic material, therefore eliminating all magnetic attraction between the rotor and the stator. As shown in the image below, this feature enables lightweight, flexible stator and rotor support structures.
