Patent ID: 8861776

Claim:
An electromechanical conversion system comprising: a fixed supporting structure; a movable element, said movable element being movable with respect to the fixed supporting structure according to a direction of motion; at least one excitation coil comprising a strip shaped conductor wound about a coil axis, said coil axis being orthogonal to said direction of motion of said movable element, said movable element being arranged outside said excitation coil; at least one magnet for generating an excitation magnetic field, wherein said at least one magnet is integral with the movable element and said excitation coil is integral with the fixed supporting structure, said at least one magnet comprising poles, said poles being aligned orthogonal to said direction of motion; and a ferromagnetic circuit cooperating with said at least one magnet, said ferromagnetic circuit being fixed with respect to said fixed supporting structure, wherein a plurality of plates of ferromagnetic material forming part of said ferromagnetic circuit are inserted between turns of said excitation coil.
