Abstract
A color wheel is attached to a hub of a motor before the hub is built in the motor. In this process, portions of the hub which do not impact the rotation accuracy of the motor are held by appropriate clamping means and attaching means so that excessive stress and heat are not applied to bearings of the motor. Then, the hub with the color wheel attached thereto is assembled to the rest of components of the motor.
