More Information
Summary:An apparatus, according to one embodiment, includes: a support plate, a stator, and a stator support arm. The stator support arm has a first end that is coupled to the support plate, and extends from the support plate to the stator. Moreover, the stator is coplanar with the support plate. The apparatus further includes at least one isolation mount, and a rotor sub-assembly. The isolation mount is 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. The rotor sub-assembly includes a magnet, and a hub rotatably fixed relative to the magnet. Furthermore, the rotor sub-assembly is configured to rotate relative to the support plate and the stator. Other systems, methods, and computer program products are described in additional embodiments.
