2.4 Drive Box

The Drive Box contains the electronic components that take 110-230 VAC at 50/60 Hz from the boat’s generator or shore power and supply current to the flywheel motor according to commands from the Electronic Control Module (ECM). The glycol/water mix that cools the Seakeeper is also circulated through a cold plate inside the Drive Box to remove heat from high-power electronic components.

The Drive Box contains high voltage electronics and the cover should not be removed while the flywheel is spinning except by an authorized technician. This high voltage exists even if the flywheel is coasting down and the supply voltage has been shut off.
