Abstract
An atomizer for mounting on an output shaft of a motor to be rotated by the motor includes a front surface, a back surface, a coating material cup into which coating material to be atomized by the atomizer is dispensed, and at least one passageway from the cup to the front surface to permit the flow of coating material from the cup to the front surface as the atomizer is rotated. The front surface terminates at a discharge edge from which the coating material is discharged as the atomizer is rotated. The atomizer/shaft comprises an electrically conductive first electrode, an electrically non-conductive portion, and a semiconductive coating provided on the back surface. The semiconductive coating terminates adjacent the edge.
