Patent attributes
A flywheel/motor assembly is disclosed that comprises a motor housing having a sidewall and an end wall extending substantially perpendicularly from the sidewall. The end wall enclose a motor assembly having a rotatable shaft extending therefrom. The motor housing has at least one air flow opening therethrough. A flywheel is coupled to the shaft, and includes a pulley side and a motor side opposite the pulley side, wherein the motor side is aligned substantially with the end wall and does not extend over the sidewall. A plurality of vanes are associated with the flywheel, wherein adjacent vanes form channels therebetween. A ring is coupled to the plurality of vanes and at least partially encloses the channels and forms exhaust ports away from the shaft. Rotation of the flywheel draws air through the motor housing's openings into the channels and out the exhaust ports. The pulley side may include balancing bores for receiving balancing material to balance the finished assembly. An angular interference fit between the flywheel and motor shaft may also assist in balancing the finished assembly. A ventilation fan system may also be connected to the shaft at an end opposite the flywheel.
