ABSTRACT:
A spindle motor for rotating at least one disc in a data storage device includes a base, a shaft, a rotor and a stator. A bearing interconnects the rotor with the shaft and allows the rotor to rotate about the shaft. A resilient coupling, such as an O-ring, is compressed between the stator and the base to mechanically isolate the stator from the base and thereby reduce the generation of acoustic noise in the storage device.
