  • Patent number: 6548925
    Abstract: A flywheel having a molded cage formed around a plurality of magnets attached to the flywheel. The cage extends into one or more grooves formed in the flywheel to resist the shrinkage of the cage inside diameter as it cools following an injection molding process. The gap between the cage and magnets and an adjacent stator is precisely controlled and minimized. Shutoff surfaces formed on the flywheel function as a portion of the die for injection molding of the cage.
    Type: Grant

  • Patent number: 6339271
    Abstract: A flywheel (20) having a molded cage (30) formed around a plurality of magnets (34) attached to the flywheel (20). The cage (30) extends into one or more grooves (40,42) formed in the flywheel (20) to resist the shrinkage of the cage 30 inside diameter as it cools following an injection molding process. The gap (44) between the cage (30) and magnets (34) and an adjacent stator (32) is precisely controlled and minimized. Shutoff surfaces (36,38,46) formed on the flywheel (20) function as a portion of the die for injection molding of the cage (30).

  • Patent number: 5573436
    Abstract: An improved air inlet cover for use with outboard motors is disclosed. A particular embodiment of the cover is formed by a generally hollow shell having an open side. An air passage is located opposite the open side at an upper portion of the shell. A baffle extends from an upper inner portion of the shell to an elevation below the air passage and is disposed generally opposite the air passage. An exit port is provided at the bottom of the chamber for discharging water collected therein, and a valve is provided within the exit port. When the exit port is submerged the valve is closed and provides a barrier to water entry. Preferably, the cover is located at an upper forward portion of the outboard motor cowl and both the air passage and air inlet are high up on the upper forward portion.
