Abstract (en)
[origin: WO2019077261A1] The invention relates to an electric machine having a rotor (11a, 11b, 11c) comprising a set of permanent magnets (13a, 13b, 13c, 13d, 13e, 13f, 13g) and a stator comprising a stator strip (1) made of a soft ferromagnetic material, said strip (1) supporting a coil body (4) having a single discontinuity, said coil body (4) supporting a plurality of wire coils (8) so as to form a polyphase coil stator assembly (10) of the toroidal type, characterised in that said strip (1) has a single discontinuity and has at least one partial cut (2) at regular intervals between two consecutive wire coils (8).
