A torque motor for a servovalve, said torque motor comprising: a set of pole pieces comprising a first pole piece and a second pole piece, wherein the first and second pole pieces (1,5) each have a C-shaped cross section, wherein each of the first pole piece and the second pole piece has a ring shaped section (1b, 5b) extending in a first plane and a first portion (1c, 5c) extending in a direction perpendicularly away from the plane of the ring shaped section (1b, 5b); an armature provided between the perpendicularly extending portions (1c, 5c) of the first pole piece and the second pole piece, said armature configured to provide air gaps (AG1-AG4) between the armature and the first pole piece, and the armature and the second pole piece; wherein the armature is configured to rotate about a centre point; wherein, upon assembly, the first pole piece and the second pole piece are positioned such that the perpendicularly extending portions (1c, 5c) face each other and also face the armature which is positioned therebetween; characterized in that adjacent the ring shapes section (1b, 5b), and on the opposite side of the extending portions (1c, 5c), is provided a tapered ring section (1a, 5a) which tapers from the ring shaped section (1b, 5b) to a surface (1d, 5d) of the first and second pole pieces (1, 5); in that the tapered portions (1a, 5a) are spherical and rotate in a spherical area; in that the outer surfaces (1d, 5d) are spherical; in that the midpoint of the spherical area is the centre point on which the armature rotates; and in that the set of pole pieces is adapted to rotate around the centre point such that the air gaps (AG1-AG4) can be adjusted. a set of pole pieces comprising a first pole piece and a second pole piece, wherein the first and second pole pieces (1,5) each have a C-shaped cross section, wherein each of the first pole piece and the second pole piece has a ring shaped section (1b, 5b) extending in a first plane and a first portion (1c, 5c) extending in a direction perpendicularly away from the plane of the ring shaped section (1b, 5b); an armature provided between the perpendicularly extending portions (1c, 5c) of the first pole piece and the second pole piece, said armature configured to provide air gaps (AG1-AG4) between the armature and the first pole piece, and the armature and the second pole piece; wherein the armature is configured to rotate about a centre point; wherein, upon assembly, the first pole piece and the second pole piece are positioned such that the perpendicularly extending portions (1c, 5c) face each other and also face the armature which is positioned therebetween; characterized in that adjacent the ring shapes section (1b, 5b), and on the opposite side of the extending portions (1c, 5c), is provided a tapered ring section (1a, 5a) which tapers from the ring shaped section (1b, 5b) to a surface (1d, 5d) of the first and second pole pieces (1, 5); in that the tapered portions (1a, 5a) are spherical and rotate in a spherical area; in that the outer surfaces (1d, 5d) are spherical; in that the midpoint of the spherical area is the centre point on which the armature rotates; and in that the set of pole pieces is adapted to rotate around the centre point such that the air gaps (AG1-AG4) can be adjusted.
