Abstract
An apparatus, according to one embodiment, includes: a support plate, a stator, at least one isolation mount coupled between the support plate and the stator for reducing transfer of vibration from the stator to the support plate, and a rotor sub-assembly. Furthermore, 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.
