A piece-part microactuator (220), or micromotor, manufacturing approach is presented. In this approach, two of the NiFe parts (221,223) and dielectric and copper (225) piece-parts are manufactured separately. This allows the NiFe parts (221,223) to be designed in a manner to maximize the thickness of the metal, which in turn increases the magnetic properties of the motor. The dielectric and copper coils piece-part (225) may be based upon a thin film interconnect (222) or some derivative of a standard flex circuit printed wiring board. These piece-parts (221,223,225) may be tested individually, defective parts discarded, and only functional units assembled. This not only produces a mechanically balanced construction, but has lower cost due to non-sequential manufacturing steps. The dielectric and copper coils piece-part (225) also provides the path for electrical connections to the movable platform (234) and a relatively easy method for electrical connection off the microactuator and onto the hard disk drive system.
