Abstract

A direct current electric motor (10), particularly for movements on motor vehicles, such as window winders, seat adjusters, windscreen wipers and the like, comprising a carcase (11) for containing a stator body with at least two poles, a rotor (12) with at least eight slots, a drive shaft (13) with commutator (14) and brushes (15), each of the brushes (15) being held in a corresponding seat (16), with radial advancement due to consumption of the brush (15), the seats (16) being formed on a brush holder body (17) to be fixed to the carcase (11). The arc of contact between the projecting end of a brush (15) and the commutator (14) has a diameter (Dl) that is equal to the diameter (D2) of the commutator (14), or which differs from it by less than 10% of the diameter (Dl) of the commutator, and each brush holder seat (16) has two lateral walls (18, 19), with positions that are parallel to each other and which are parallel to the axis of rotation of the motor, and two walls (24, 25) that are perpendicular to the previous walls, with positions that are therefore substantially perpendicular to the axis of rotation of the motor, one of these walls being shaped so as to form the stroke limit for the corresponding brush (15), so having an abutment surface (26) for the power braid (27) fixed to the brush (15).
