Abstract: Described is a generator for an engine-driven power system. The generator having a generator shaft, a sleeve coupler, a first pulley, and a second pulley. The generator shaft, which is shaped at an end to define a first tapered surface, rotates a rotor relative to a stator. The sleeve coupler is shaped to define a bore with a second tapered surface. The bore receives the end of the generator shaft. The first pulley has a center hole to receive the sleeve coupler. The second pulley shares an axis of rotation with the first pulley and transfers a rotational force to the generator shaft and to the sleeve coupler.

Abstract: Described is a power system having an engine, a generator, a belt-driven component, a first pulley, a second pulley, a third pulley, and a fourth pulley. The engine outputs a rotational force at a first rotational speed to rotate the first pulley. The generator converts mechanical power driving the generator shaft to electric power. The second pulley is drivingly coupled to the first pulley via a first belt and configured to rotate the generator shaft at a second rotational speed based on the first rotational speed. The fourth pulley coupled to the generator shaft having a first diameter that is greater than a second diameter of the second pulley. The fourth pulley configured to drive the third pulley at a third rotational speed to drive the belt-driven component

Abstract: Power systems and methods of controlling an engine driven air compressor include an air compressor driven by an engine via a clutch. A first pressure sensor configured to sense a pressure level at an outlet of the air compressor. An inlet valve configured to close in response to the first pressure sensor sensing a pressure level above a first pressure level. In addition, a second pressure sensor to sense a pressure level below a second pressure level at a housing of the air compressor, wherein the clutch is configured to disengage in response to the second pressure level, wherein the first pressure level is higher than the second pressure level.

Abstract: Power systems and enclosures having improved cooling air flow are disclosed. An example power system includes an enclosure; an air inlet location at a first location on an exterior of the enclosure to permit intake of air from the exterior of the enclosure to an interior of the enclosure; an air exhaust location at a second location on the exterior of the enclosure to exhaust the air taken in through the air inlet location; and an air routing path defined by the enclosure to direct the air from the air inlet location to the air exhaust location, in order: through one or more first compartments in the enclosure, the one or more first compartments containing at least one of a compressor, a generator, or power conversion circuitry; and through one or more second compartments, the one or more second compartments comprising an engine and a muffler.
