Abstract
Planar magnetic motor (100), characterized by the fact that it comprises a plurality of magnetic poles (111, 121) made of a ferromagnetic material placed at the center of planar coils (110, 120) constituted by at least one layer of turns produced on the surface of a substrate (150) made of a ferromagnetic material, the turns being wound and connected to each other so as to combine the magnetic fluxes generated by the magnetic poles (111, 121). The invention can be used to produced magnetic motors and microactuators.
