The flywheel spins about a vertical axis and is supported by upper and lower pairs of bearings. A DC brushless motor mounted inside the enclosure spins the flywheel at high speed. <\/p>\n\n\n\n<p>The enclosure is fastened to two gimbal shafts that are supported by gimbal bearings on either side. These shafts establish an athwartship gimbal axis about which the flywheel and enclosure precess or rotate up to <br>+\/- 67 degrees during operation. The gimbal bearings are supported by a foundation which is attached to the hull structure. This foundation transfers the loads that the <span translate=\"no\">Seakeeper<\/span> produces to the hull structure. <\/p>\n\n\n\n<p>An active hydraulic brake mechanism is located on the <span translate=\"no\">Seakeeper<\/span> assembly to regulate the <span translate=\"no\">Seakeeper<\/span>\u2019s precession motions about the gimbal shaft. It includes two hydraulic cylinders and a hydraulic manifold. <\/p>\n\n\n\n<p>A coolant pump, heat exchanger, and reservoir are located near the manifold. A glycol\/water mix is circulated through a closed loop to the drive box, hydraulic manifold, and the end caps of the enclosure to remove heat.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-content\/uploads\/SK3-CBRO-w-Callouts-1-3000x1816.png\" alt=\"\" class=\"wp-image-16166\" width=\"660\" height=\"400\" srcset=\"https:\/\/manuals.seakeeper.com\/seakeeper\/wp-content\/uploads\/SK3-CBRO-w-Callouts-1-3000x1816.png 3000w, https:\/\/manuals.seakeeper.com\/seakeeper\/wp-content\/uploads\/SK3-CBRO-w-Callouts-1-768x465.png 768w, https:\/\/manuals.seakeeper.com\/seakeeper\/wp-content\/uploads\/SK3-CBRO-w-Callouts-1-1536x930.png 1536w, https:\/\/manuals.seakeeper.com\/seakeeper\/wp-content\/uploads\/SK3-CBRO-w-Callouts-1-2048x1240.png 2048w\" sizes=\"auto, (max-width: 660px) 100vw, 660px\" \/><figcaption class=\"wp-element-caption\"><em><span translate=\"no\">Seakeeper<\/span> Assembly<\/em><\/figcaption><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The Seakeeper assembly consists of a flywheel housed in a cast aluminum vacuum-tight enclosure.
