For grounding or electrically charging the shaft of an electrostatic rotary atomizer working with external or direct charging, there are opposing, annular or spiral-shaped sharp edges in the outer surface of a part of the shaft and in the inner surface of a stationary bearing part at the desired potential, which have different, preferably opposite, thread directions, so that the edges intersect each other at points.

Potential neutralization arrangement for an electrostatic rotary atomizer

A turbine, e.g., with a blade arrangement, which receives an air flow in the radial direction and which is located on a carrier surface of the turbine wheel, is used as a drive motor for a rotary atomizer. The drive channel, which contains the turbine blades and which is limited by the carrier surface, is also closed on its other side by a cover element, which is attached to the turbine wheel and which rotates with the wheel for increasing efficiency. For an additional increase in efficiency, the inlet for the drive air of the turbine is configured as an ultrasonic nozzle with a cross section that expands continuously up to the opening.
