Abstract

In one example, an electrostatic spray gun includes a spray tip assembly, an alternator, an electrode, and at least one controller. The alternator includes a stator having an inner diameter and an outer diameter. The alternator further includes a rotor disposed within the inner diameter of the stator and configured to rotate within the stator to cause the alternator to generate alternating electrical current. The electrode, positioned proximate the spray tip assembly, is coupled to receive electrical energy from the alternator. The at least one controller is coupled to the alternator and is configured to output a representation of a rotational speed of the rotor.
