To provide an improved biaxial type pointing motor.
There is provided an improvement of a biaxial pointing motor 20 including a frame 21 and an armature 22. The armature 22 has the axis x-x passing the point P. The armature 22 is mounted on the frame 21 to control the full-direction pivot movement of the axis around the point. The motor 20 has a permanent magnet 24 mounted on the armature 22 and a plurality of coils 25 which are mounted on the frame 21 to generate the electromagnetic flux to be controlled to pivot the armature 22 around the point. In one hand, improvement includes that of a coil to be positioned to perfectly provide the total volume of each coil within the virtual hemi-sphere (h) generated around the point. This semi-sphere has the radius determined freely but surrounds the coil. On the other hand, improvement includes that of armature having the magnetic conductive surface 33 which is formed as a segment of sphere.
