Abstract
A fan-flywheel-pulley assembly for use in conjunction with an electric motor. The assembly may include a pulley positioned about a central axis. The assembly may also include a flywheel coupled to the pulley and positioned about the central axis, the flywheel including an outer circumferential flywheel surface partially forming a plurality of circumferentially spaced openings. The flywheel may also include a baffle that extends circumferentially in close proximity to a cylindrical wall unit of the motor from an inner diameter to an outer diameter to limit a gap between the baffle and the cylindrical wall unit. Further, the assembly may also include a radial fan disposed within the flywheel including a plurality of blades extending at least from the flywheel inner diameter to the outer diameter each opening is positioned between each adjacent fan blade. The pulley, the flywheel, and the radial fan may be integrally formed.
