Abstract (en)
[origin: EP1237058A1] The micro-generator (1) includes magnetic parts (5) and is partially surrounded by non magnetic parts (11,12) covered by a finishing cover. The finishing cover covering the rough finish parts (11,12) situated in proximity to the micro-generator has essentially non-magnetic properties. The covering includes at least two metallic layers, and at least those in contact with the parts (11,12) contains nickel forming part of a non-magnetic alloy. The micro-generator (1) has a rotor (2) including two disk flanges (3). Each disk has on its face opposite the other a number of magnets (5). The micro-generator has also an electronic module (6) including at least a stator winding (4) partially inserted between the two disk flanges (3). The generator is partially situated in a volume delimited by the orthogonal projections from the parts (11,12). The generator detects the presence of an external magnetic field and assures the operation of a compass.
