ABSTRACT:
A method for balancing the rotor of a wind turbine and a balancing weight. The weight is formed of a piece of steel or other material of sufficient weight bent in an L shape with holes that allow it to be bolted onto a flange at the root of the wind turbine's blades. The width, thickness, or length of the weight can be varied to produce balancing weights of unique weight and radius from the rotor's axis of rotation. A trial weight is disclosed for use with the so-called four run method of determining the rotor's unbalance. The trial weight can be quickly and easily attached and removed.
