Claim 0:
1. An electric machine having a rotor comprising a set of permanent magnets and at least one toroidal polyphase coil stator assembly comprising a stator strip made of a soft ferromagnetic material, the strip slidably is received within an elongated opening between flanks of a continuous unitary coil body, said unitary coil body having a plurality of spaced-apart receiving zones around which a plurality of wire coils are wound so as to form the toroidal polyphase coil stator assembly, said spaced-apart receiving zones coupled together with flexible bridges to form the continuous unitary coil body, the strip periodically having at least one partial cut between two consecutive wire coils in order to obtain a polygonal shape of the strip inside the plurality of wire coils.
