A cover for a rotating electric machine includes an axis of rotation (X), the cover being designed to be arranged on an inverter of the machine. The cover includes a skirt extending in a radial direction and forming a perimeter of the cover, the perimeter defining an inner portion of the cover and an open area arranged in the inner portion and comprising at least one axial opening. The open area extends over at least 50% of the inner portion of the cover.

The device according to the invention controls a polyphase inverter () intended for powering from a DC current source (CC) a polyphase rotating electric machine (). The device is of the type of those generating commutation functions driving commutation elements () of the inverter in such a way as to obtain a reduction of the losses in the commutation elements and a decrease of an effective current in a decoupling capacitor () of the source (CC). According to the invention, this reduction and this decrease are obtained by means of a set of control strategies () determining the commutation functions by using additional degrees of freedom of the polyphase machine () with respect to a three-phase reference machine. The polyphase machine comprises first and second phase windings forming a first three-phase system () and a second three-phase system () with distinct neutral points () offset angularly by a predetermined angle of offset (&#x398;). The first and second phase windings are linked respectively to three first and three second power arms () formed by the commutation elements.
