Rotary electric machine for a motor vehicle includes a stator, extending along an axis, the stator including a body and a winding provided with lead-out wires extending axially on either side of the stator body. At least one end shield includes a plate extending transversely and a skirt extending axially from the plate, the plate having an inner face oriented towards a lead-out wire of the winding. The inner face includes a main recess which increases the minimum axial distance separating the lead-out wire from the inner face, the main recess having a bottom extending radially.

A driving device includes an electric motor, a rotating shaft, a motor housing, a printed circuit board, an electric power converting circuit, a rear frame end working as a heat radiating member, gel working as a heat transfer member, multiple mounted parts and so on. The heat radiating member is located on a side of the printed circuit board and facing a motor-side surface of the printed circuit board, to which multiple switching elements are mounted. The gel is plastically deformed and adhered to the switching elements and the heat radiating member for transferring heat of the switching elements to the heat radiating member. At least one of the mounted parts is mounted to the printed circuit board and located at a position between a through-hole opposing area and one of the switching elements, which is located at a position closest to a rotational angle sensor mounted to the printed circuit board in the through-hole opposing area.
