Abstract: A rotary atomizer has an internal power supply in the atomizer housing about which is passed cooling air. The air then flows out of the atomizer housing in a twisting direction as vectored air in the same direction of rotation as the atomizer head to eliminate any vacuum condition around the atomizer head and to provide shaping control of the coating being sprayed. A portion of the exhaust air from an air turbine motor driving the atomizer head with a turbine shaft is directed through a passageway between a stationary fluid tube within the turbine shaft and the rotary shaft to direct the exhaust air into the atomizer head to mix with the coating and create an air barrier that prevents coating material from leaking back into the rotary atomizer device. The remaining portion of the exhaust air from the air turbine motor is channeled around the outside surface of the housing of the rotary atomizer device to prevent liquid coating material from wrapping back and attaching to the atomizer housing.

Abstract: A rotary atomizer has an internal power supply in the atomizer housing about which is passed cooling air. The air then flows out of the atomizer housing in a twisting direction as vectored air in the same direction of rotation as the atomizer head to eliminate any vacuum condition around the atomizer head and to provide shaping control of the coating being sprayed. Exhaust air from an air turbine motor driving the atomizer head is directed around the outside surface of the atomizer housing to prevent the liquid coating from wrapping back and accumulating onto the atomizer housing. A speed sensing system is mounted in the atomizer housing and utilizes both magnetics and optics for accurately measuring the rotational speed of the air turbine motor in the presence of high electrostatic charge and RF fields from the internal power supply. The power supply is disposed within the atomizer housing about the turbine motor.
