Abstract
A torquer assembly is to exert torques about two mutually orthogonal axes on a platform which is mounted for universal movement about a central swivelling point. To this end, a stator having four pairs of pole pieces is provided. The pole pieces are angularly spaced by 90.degree. about an axis passing through the swivelling point. The pole pieces of each pair define an air gap therebetween. The air gap is limited by spherical surfaces. The spherical surfaces are curved about the swivelling point. Permanent magnets together with the pole pieces and magnetic return loops form magnetic circuits, a magnetic field being generated in the air gaps. An armature with four elongated, arcuate coils angularly offset with respect to each other by 90.degree. is connected with the platform. The coils have circumferentially extending turns. Each of these coils extends, with an arcuate coil section, into the air gap of a respective one of the pairs of pole pieces.
