Embodiment Construction

[0067] The drawings are given by way of example and do not limit the invention. The drawings constitute schematic diagrams for facilitating the understanding of the invention, and are not necessarily to scale of actual application. In particular, the dimensions of the different parts do not represent reality.

[0068] Refer to all drawings (especially Figure 4 , Figure 5a , Figure 5b , Figure 6a with Figure 6b , also referring to the other figures for the missing reference numerals on the preceding figures), the invention relates to a three-dimensional magnet structure 6 which is composed of a plurality of unit magnets 4 . The magnet structure 6 may take the form of a sheet having a width, a length and a thickness, the thickness forming the smallest dimension of the magnet structure 6 .

[0069] According to the invention, said magnet structure 12 is integrated with at least one grid structure 5 a having meshes each delimiting a housing 5 or honeycomb slot for a res...

Abstract

The present invention relates to a three-dimensional magnet structure (6) made up of a plurality of individual magnets (4), the magnet structure (6) having a thickness that forms its smallest dimension, the magnet structure (6) incorporating at least one mesh (5a) exhibiting mesh cells each one delimiting a housing (5) for a respective individual magnet (4), each housing (5) having internal dimensions just large enough to allow an individual magnet (4) to be inserted into it, the mesh cells being made from a fibre-reinforced insulating material, characterized in that a space is left between the housing (5) and the individual magnet (4), which space is filled with a fibre-reinforced resin, the magnet structure (6) comprising a non-conducting composite layer coating the individual magnets (4) and the mesh structure (5a).

Description

technical field [0001] The invention relates to a magnet structure with a plurality of unit magnets integrated in a grid structure. The invention also relates to an electromagnetic actuator comprising one or more such magnet structures. Background technique [0002] The invention finds an advantageous, but not limited, application to electromagnetic actuators for transmitting high power and rotors with high rotational speeds, obtained by using one or more configurations of magnets according to the invention. Such electromagnetic actuators can be used, for example, in all-electric or hybrid motor vehicles. [0003] Advantageously but not limitatively, said actuator may be a rotary actuator, said actuator may comprise at least one rotor surrounded by two stators, these elements may be positioned one relative to the other on the same axis. stacked one on top of the other while being separated by at least one gap. [0004] In high-speed applications, not only a compact system...
