Abstract

An improved torque motor (100) for use in a servovalve is described herein, comprising: first and second pole pieces (20', 20"), having a C-shaped cross-section comprising a ring shaped section (20a, 20b) extending in a first plane with first (20c, 20e) and second portions (20d, 20f) extending perpendicularly away from said plane and inwards towards an armature plate (50). The perpendicularly extending portions (20c-20f) are detachable from and attachable to the ring-shaped section (20a, 20b) of the pole pieces (20', 20") to allow for easier calibration and adjustment of the air gaps between the pole pieces and the armature plate positioned there between. An improved method for calibrating the air gaps in a torque motor (100) of a servovalve is also described herein comprising: assembling the torque motor (100) and after assembly, measuring the air gaps e<1>- e<4>between the perpendicularly extending portions (20c-20f) of the pole pieces and the armature plate (50), then detaching and removing these perpendicularly extending portions (20c-20f) of the pole pieces; altering their dimensions and re-attaching the perpendicularly extending portions (2c-2f) to said ring-shaped section (20a, 20b) to produce the correct air gap sizes.
