Abstract (en)

[origin: WO2007138211A1] A triphase rotating electric machine includes three coils (2) evenly distributed around a rotational axis of the machine, and at least one first sensor (4), capable of generating a periodic signal to represent the position of the machine around said axle and a control circuit (8) capable of controlling, when in the first mode, the conduction of a switch (KUH), linked to at least one of the three coils (2) based on the periodic signal generated by the first sensor (U), such that the conduction phases of the switch (KUH) have a duration in the order of half the signal period (U). The control circuit is capable of controlling the switch (KUH), based on a second mode in which the conduction phases of the switch (KUH) have a duration in the order of a third of the signal period (U).
