Abstract
A well servicing pump system for a hydraulic fracturing system includes a first permanent magnet motor, second permanent magnet motor, and crankshaft. The first and second permanent magnet motors each include a rotor mechanically coupled to or integrated with the crankshaft. The well servicing pump may include gearboxes coupled between the rotors and the crankshaft. The well servicing pump system also includes a fluid section that includes an inlet, a pressurization chamber, and an outlet. The inlet and outlet are fluidly coupled to the pressurization chamber. The well servicing pump also includes a plunger mechanically coupled to the crankshaft, the plunger at least partially positioned within the pressurization chamber.
