ABSTRACT:
A novel design concept for a torquer motor is useful for stabilizing apparatuses in a vibrating structure. According to one aspect, a novel design for a coil pair is provided. A first coil in the pair is box shaped with a hollow interior portion and windings provided on a surface opposite the hollow interior. A second coil in the coil pair is flat and torus shaped with windings provided on the surface. According to one example, the second coil is bent so as to conform to the shape of the first coil, and disposed over the first coil so that the respective windings are oriented orthogonally to each other in a common plane direction so as to define an active area. The active area may be further disposed in the magnetic field of a magnet pair in a torquer motor application. The design provides advantages such as inherent rigidity and more efficient heat transfer, while providing high torque or a desired range of movement. Alternative designs consistent with the above approach are disclosed, which provide similar advantages over the prior art.
