ABSTRACT:
A rotary atomizer having a low capacitance, cup-shaped, atomizing head mounted for rotation about an axis of rotation has a coating material flow surface forming a forward cavity. A rotary drive coupled to the atomizing head rotates the atomizing head about the axis of rotation. High voltage electrostatic energy is conducted through the rotary drive directly into the atomizing head whereby changed coating material flows outwardly across the flow surface. In another embodiment, a semi-conductive ring is mounted on the front end of the atomizer to transfer the high voltage electrostatic energy into the atomizing head and/or to dissipate the electrostatic energy in the rotary drive or in the atomizing head.
