    Is that a big electric motor on the right side of the photo? Perhaps driving a shaft with 2 flywheels, and a small pinion gear for that monster gear? That monster generates some torque!!!

    You can see the commutators and brushes on the right. The motor turns a flywheel and the smaller gears. The large gear drives a flywheel and the machine on the left...
