The generator is preferably located between the engine and the marine drive system providing an auxiliary or primary source of substantially stabilized constant voltage constant frequency AC power from a variable speed marine engine.
Claims26
A direct coupled electrical generator for drive-line installation on a marine water craft comprising:
- a variable speed internal combustion engine providing rotational output;
- a generator having a first and second side surface, said first side surface coupled to said engine wherein said rotational output of said engine produces an electrical output;
- means for correcting said electrical output to a substantially stabilized constant AC voltage having a constant frequency;
- a marine drive system connected to said second side surface of said generator wherein said rotational output of said engine supplies rotary motion to said marine drive system during operation thereof;
- a propeller shaft having a proximal end coupled to said marine drive system and a distal end coupled to at least one propeller;
- whereby said variable speed internal combustion engine drives said propeller through said marine drive system and said generator, said generator generating an electrical output of variable voltage variable frequency and said means for correcting placing said electrical output into a substantially constant AC voltage constant frequency.
A direct coupled electrical generator for drive-line installation on a marine water craft comprising:
- a variable speed internal combustion engine having rotational output;
- a generator connected to the rotatable output of said internal combustion engine;
- an out-drive connected to said generator such that said variable speed internal combustion engine supplies rotary motion to said generator and said out-drive during operation thereof;
- a propulsion means coupled to said out-drive;
- whereby said variable speed internal combustion engine drives said generator at a variable speed which in turn generates electrical power of variable voltage and variable frequency.
In a drive train of a water craft including at least one variable speed internal combustion engine in mechanical communication with at least one power transmission device which is further in mechanical communication with at least one impeller means constructed and arranged to provide motive thrust, the improvement comprising:
- at least one generator for generating electricity, wherein said generator is constructed and arranged for direct coupling between said internal combustion engine and said power transmission device;
- means for conditioning electrical power produced by said generator to a substantially stabilized constant voltage constant frequency electrical power.
