Abstract: A method of balancing a rotor and/or fixing rotor components includes arranging a plurality of generally like laminations side by side in a stack to form at least a part of a rotor. The rotor has a rotational center axis and each of the laminations having a plurality of apertures that cooperate to form passages that extend axially along a length of the stack. In accordance with an aspect of the method, a polymer based fixation material is filled in the passages in a manner to fix the laminations together in the stack. With the fixation material, a sprue is formed, projecting from an axial face of the stack. In accordance with another aspect of the method, a weight of the sprue is adjusted to rotationally balance the rotor about the rotor center axis.
