Claim 21:
22. A hydraulic fracturing system for fracturing a subterranean formation, the hydraulic fracturing system comprising:
a plurality of electric motors;
a planetary gear train connected to the plurality of electric motors, the planetary gear train comprising:
a plurality of input pinion gears, each driven by a respective one of the plurality of electric motors;
a main gear driven by the plurality of input pinion gears, the main gear comprising external gear teeth that mate with external gear teeth of the plurality of input pinion gears;
a sun gear driven by the main gear and connected to the main gear by a shaft;
planetary gears driven by the sun gear, the planetary gears each comprising external gear teeth that mate with external gear teeth of the sun gear; and
a final drive gear driven by the planetary gears, the final drive gear comprising internal gear teeth that mate with the external gear teeth of the planetary gears; and
a multi-plunger hydraulic fracturing pump that pumps fluid to a wellbore and comprises a pump crankshaft that is driven by the final drive gear of the planetary gear train, the final drive gear connected to the pump crankshaft by a plurality of arms extending from the final drive gear.
