The invention relates to a dc electric motor, in particular of the brushless type, for a motor vehicle wiper system, comprising a stator (2) and a rotor (3), the stator (2) comprising a plurality of coils (4) for electromagnetic excitation of the rotor (3) and the rotor (3) comprising a multi-pole magnet (5) mounted so as to perform a rotational movement about an axis of rotation (L) and provided with at least two pairs of opposite poles, wherein at least three poles each have a width in a plane (P) orthogonal to the axis of rotation (L) which is different from that of the said at least two other poles, and/or three poles with the same polarity are angularly shifted.
