Abstract
A method of manufacturing a moving coil force motor particularly adapted for utilization with a hydraulic servovalve. The method includes aligning a flexure spring with respect to the permanent magnet structure and thereafter securing the permanent magnet structure and flexure spring within a case for the force motor. Subsequently, the coil structure is aligned with respect to the gap provided in the permanent magnet pole pieces by relatively moving the motorcase with respect to the coil until the appropriate position is attained and thereafter securing the case against further movements.
