Abstract
An outer barrel is configured to rotate. A first central shaft passes through the outer barrel. The first central shaft is configured to rotate with the outer barrel. A first bearing assembly is attached to the first shaft on a first side of the outer barrel. A second bearing assembly is attached to the first shaft on a second side of the barrel. The second bearing assembly supports the first shaft to an isolation can. An inner barrel is magnetically coupled to and is configured to rotate with the outer barrel. A second central shaft passes through the inner barrel. The second central shaft is configured to rotate with the inner barrel. A third bearing assembly is attached to the second shaft. The isolation can fluidically isolates the inner barrel assembly from the outer barrel assembly. The isolation can supports the second bearing assembly to the housing.
