Unbalanced hub design

A color wheel includes a hub component configured to act as a rotor coupled to an electric motor and having a disc-shaped surface; an optically active radial component attached to or integrated with the hub component and configured to optically process incident light; a balancing adapter is adapted to a disc-shaped surface of a hub component, the balancing adapter comprising one or more of: (a) a recess in the disc-shaped surface extending to an edge of the disc-shaped surface; (b) an annular groove in the disc-shaped surface, the annular groove having a non-uniform width and/or being non-concentric with the disc-shaped surface; (c) an annular groove in the disc-shaped surface, at least a portion of the annular groove being filled with a balancing mass; and (d) a matrix of grooves and/or recesses in the disc-shaped surface, the matrix of grooves and/or recesses being arranged to define a portion of an annular shape. 一种色轮，包括轮毂部件、光学主动径向部件和平衡适配件，轮毂部件构造成用作耦合到电动机的转子并具有盘形表面；光学主动径向部件附接到所述轮毂部件或与所述轮毂部件集成一体，并被构造成光学处理入射
