Application of neodymium-iron-boron permanent magnets on the assembling ofa novel planar actuator

This paper depicts a nerv planar actuator, with novel structure and constru ction features. It includes a slotless stationary plane armature and a move r with two permanent magnets. By using NdFeB permanent magnets with high-en ergy product, it became possible to develop a planar motor with a novel top ology. The planar actuator develops movement over a plane surface as a resu lt of the interaction between the magnetic flux and current established thr ough the orthogonal multiphase windings that comprehend the armature circui t. The actuator was analysed by means of the finite element method in order to compute the nux density distribution, the forces involved and improve i ts design The results are presented in this paper.
