Abstract (en)
[origin: WO2008006953A1] The invention relates to an active element (20) for an electromagnetic machine, including, along a main axis (X), an alternating succession of segments (21) having a first magnetic property and segments (22) having a second magnetic property. The invention is characterised in that the active element includes a coating (25, 25) which is thin in relation to the thickness of the segments and which extends such as to cover a substantial part of an outer surface of the active element. The aforementioned coating is solidly connected to at least some of the segments and has a sufficient mechanical strength in order to form a member for the mechanical transmission of the magnetic forces experienced by the segments.
