Abstract
An apparatus, according to one embodiment, includes: a support plate; a stator; a stator support arm having a first end that is coupled to the support plate, the stator support arm extending from the support plate to the stator. The apparatus further includes at least one isolation mount coupled between a second end of the stator support arm and the stator for reducing transfer of vibration from the stator to the stator support arm; and a rotor sub-assembly. The rotor sub-assembly is configured to rotate relative to the support plate and the stator, the rotor sub-assembly including: a magnet; and a hub rotatably fixed relative to the magnet. Other systems, methods, and computer program products are described in additional embodiments.
