“…is the electromagnetic force component produced by an x-coil section while Fy is produced by an y-coil section under the action of permanent magnet n. When the effect of both permanent magnets is considered, this results in a total force F acting on the mover that can produce a simultaneous movement along the both axis and is given by (5). The direction of F defines the direction of movement of the mover.…”

“…Fig. 4(a) shows the position of the mover located over the coil sections [4] [SI. There one permanent magnet is located over the gth x-coil section and the 5th y-coil section and the other permanent magnet, over the 1 lth x-coil section and the 7th y-coil section.…”

“…up of two combined meshes: one is the mover mesh, and the other, the stator mesh. In a first stage of the work and in order to assess the static behaviour of the planar actuator, the nonconducting regions were modelled using a scalar potential, W [5]. The boundary condition was set as B parallel.…”

“…6(c) shows a graph with the 3D distribution of flux density measured in the air gap underneath the mover at 7.0 mm above the armature core. In both graphs, (a) and (b), the computed figures are obtained through the finite element analysis and compared to the measured values resulting from the tests on the actuator [4][5]. Through the numerical analysis, the peak value of the z-component of flux density in the air gap under the permanent magnets was 0.33 T, with no current in the sections of the windings, while the value measured was around 0.30 T. When current applied to each coil section is 3.0 A, the peak value of the z-component of flux density in the air gap under the permanent magnets, obtained through numerical analysis, was 0.33 T, while the value measured was around 0.31 T. With current density applied to the coil sections it is observed a strong distortion of magnetic flux lines, and a non-uniform distribution of the magnetic flux in the air gap due to armature reaction.…”

Abstrm-A novel electromagnetic planar actuator has beeninvestigated. This type of actuator can be used in positioning systems that require bi-dimensional movement over a plane, e.g. printed circuits movers and numerically controlled (NC) machines. Its design comes as an interesting option to replace the well-known xy tables based on two rotary or on two linear motors since it uses a single actuator to produce planar movement. The position of its mover depends on the resultant force vector. This paper analyses the static forces numerically obtained and compares them to the experimental results measured by means of specifically designed test setup.

The control behaviour of an electro-dynamic motor, also known as a moving coil motor, is excellent in comparison with other motor types. The same holds for the linear version of this motor type. The classical solution to realise an X-Y movement with a long stroke is to apply an H-like stacking of at least two linear motors. A rising moving mass, combined with a limited mechanical stiffness, constrains the obtainable bandwidth. An alternative is the planar motor, which generates x-and y-movements.This paper describes an electro-dynamic planar motor, which elevates and propels itself over long x-and y-strokes under full control over six degrees of freedom (6-DOF).
