Abstract

The present disclosure relates to a drive system for a blowout preventer (BOP). The drive system includes a first pseudo direct drive (PDD) motor assembly having a first PDD motor and a second PDD motor assembly having a second PDD motor. The first PDD motor is configured to engage with a first shaft coupled to a first ram of the BOP and the second PDD motor is configured to engage with a second shaft coupled to a second ram of the BOP. The first PDD motor and the second PDD motor are operable to induce translation of the first shaft and the second shaft, respectively, to drive the first ram and the second ram toward one another along a longitudinal axis to reach an engaged configuration in the BOP.
