Abstract
An outboard motor comprises an engine contained within an engine compartment formed within a power head of the motor. The engine includes a generator having a stator and a rotor. The stator is cooled by a cooling component to reduce the operating temperature of the stator. The cooling component generally comprises a heat transfer plate or cooling jacket that is positioned adjacent to at least a portion of the stator to usher heat build-up away from the stator portion of the generator. The cooling jacket may be in fluid communication with other cooling jackets or may be a discrete system that is separate and distinct from other cooling systems of the motor.
Claims19
An outboard motor comprising an engine, a crankshaft extending from the engine in a generally vertical direction, a bearing housing supporting a bearing that journals a portion of the crankshaft, a generator positioned proximate the portion of the crankshaft, the generator comprising an armature and a rotor, the armature supported by the bearing housing, the armature comprising a stator and a plurality of coils, and a heat transfer element positioned between the stator and the bearing housing.
A generator and cooling arrangement comprising a rotor and an armature, the rotor having at least one surface facing the armature, the rotor carrying at least one magnet on the surface facing the armature, the armature comprising a stator and a plurality of coils attached to the stator, the coils positioned in close proximity to a circumference defined through the magnet from a center of rotation of the magnet about the armature, a cooling member positioned adjacent a surface of the armature extending among the plurality of coils, the cooling member having a component made of a thermally conductive material.
