A motor assembly integrates a motor mounting structure and electrical connection parts achieving reduced motor component count and assembly cost. The motor assembly includes a mounting structure integrally formed into a motor coil support with plastic overmold. A plurality of connector pins are molded into the coil support for electrically coupling the motor to a printed circuit board (PCB).

Motor with overmold coil support

A voice coil rotor is formed with a metal hub alignment insert for interiorly receiving an assembly of bearings and for exteriorly receiving and retaining at least two head arms against radial walls of an integral annular spacer ring portion. An overmolded plastic hub encapsulates at least one leg of a generally trapezoidal voice coil as well as the exterior of the metal hub alignment insert and adjacent portions of the head arms attached thereto.

Low cost plastic overmolded rotary voice coil actuator

An aerodynamic actuator filter-latch for releasably locking a rotary voice coil actuator within a hard disk drive includes a shaft and a rotating latch structure on the shaft. The latch structure includes an airvane portion extending across a rotating disk adjacent one of the major surfaces thereof, a central portion including an air filter for removing minute particulate contaminants from air within the enclosed head and disk assembly, the air filter being located adjacent to a periphery of the disk, and an actuator latch portion extending toward the rotary voice coil actuator. The aerodynamic actuator filter-latch also includes a bias force mechanism for biasing the latch structure toward an actuator latch position in the absence of airflow. Rotation of the data storage disk causes the latch structure to rotate to a release position while some resultant airflow through the air filter removes contaminants.
