Abstract: The present invention is directed to a miniature hard disc drive having a metal base plate, an actuator assembly wherein the actuator assembly comprises a plurality of bearings, a shaft, and a housing; a spindle motor assembly comprising a stator with conductors, a shaft, a plurality of bearings, and a rotor; and a monolithic body of phase change material unitizing said actuator assembly housing and stator to the base plate. Methods of developing and constructing the hard disc drive are also disclosed.

Abstract: A motor comprises a baseplate, a shaft supported by said baseplate, a stator assembly having windings, the stator being rigidly attached to said baseplate, and injection molded thermoplastic material encapsulating said windings. In one embodiment, the stator is coreless. In other embodiments, the stator has a core and the core is substantially encapsulated by the thermoplastic material. In preferred embodiments, the thermoplastic material secures the stator to the baseplate or forms the baseplate.
