Abstract
Methods and systems are provided for a starter motor system for cranking an engine. In one example, a starter motor system includes, a battery, two electric motors arranged in series, two main contactors, two auxiliary contactors, and two solenoid contactors. Each of the two electric starter motors may be simultaneously energized to crank the engine in tandem after the pinion gears of both the electric motors are coupled to the ring gear of the engine.
