Multi-motor electrical generator system

A power generation system comprising:

• an engine having an engine output driveshaft;
• a trailer having an upper trailer bed surface with the engine mounted on the upper trailer bed surface;
• a generator assembly coupled to the output shaft of the engine, the generator assembly comprising:
• a gearbox housing mounted on the upper trailer bed surface, the gearbox housing having a first exterior side and an opposing second exterior side, where the first exterior side and the second exterior side are parallel with one another;
• a gear assembly input driveshaft disposed along a primary gear assembly axis, the input driveshaft extending from the gearbox housing and coupled to the output shaft of the engine;
• a drive gearset coupled to the input driveshaft and enclosed within the gearbox housing;
• at least three gear assembly output driveshafts, each of the at least three gear assembly output driveshafts coupled to a separate output gearset with each of the output gearsets enclosed within the gearbox housing and meshed with the drive gearset, wherein each of the at least three output driveshafts are parallel with, but spaced radially outward from the primary gear assembly axis;
• at least three primary stand-alone electric generators, each stand-alone electric generator having its own electric generator housing separate from and spaced apart from the housings of the other stand-alone electric generators and each electric generator mechanically coupled to a separate one of the output driveshafts of the gear assembly, wherein each electric generator is mounted on an exterior side of the gearbox housing allowing said electric generator to be individually maintained or taken off-line without impacting operation of the power generation system.

• at least four gear assembly output driveshafts, each of the at least four gear assembly output driveshafts extending along a separate output driveshaft axis and each of the at least four gear assembly output driveshafts coupled to a separate output gearset enclosed within the gearbox housing with each of the output gearsets meshed with the drive gearset, wherein each of the at least four output shafts is parallel with, but spaced radially outward from the primary gear assembly axis;
• at least one electric generator mechanically coupled each of the at least four gear assembly output driveshafts, each electric generator being a stand-alone electric generator having its own electric generator housing separate from the gearbox housing and separate from and spaced apart from the housings of the other stand-alone electric generators, allowing said electric generator to be individually maintained or taken off-line without impacting operation of the power generation system;
• a separate inverter mounted on each of the electric generator housings;
• an engagement mechanism disposed along each of the output driveshafts to allow each electric generator to be engaged and disengaged from its output gearset during operation of the power generation system;
• and
• a platform supporting the engine and gearbox housing, wherein the platform comprises a bed and at least a portion of the electric generators are spaced apart from the platform above the platform bed.
