Abstract
An alternator, such as for use in an electrostatic spray gun, comprises an alternator housing, a stator, a rotor, a shaft, a first bearing and a sheath. The stator is inserted into the alternator housing and has an inner diameter and an outer diameter. The rotor is disposed within the inner diameter of the stator. The shaft extends from the rotor and is rotatably supported by a first bearing. The sheath surrounds the outer diameter, supports the stator with respect to the alternator housing, and supports the bearing.
