Abstract: A stator body for an electric motor is disclosed. The stator body includes a yoke of generally cylindrical shape and including a plurality of axial notches on its inner surface, and a star including a plurality of teeth extending radially, the end of which has a shape complementary to the notches of the yoke. The star is configured to be inserted inside the yoke by axial translation. The yoke includes at least one recess formed next to at least one notch of the plurality of notches in an axial direction to allow bending of the adjacent wall of the notch during insertion of the star into the yoke. Alternately, the star includes at least one recess formed in at least one tooth of the plurality of teeth of the star in an axial direction to allow bending of the adjacent wall of the tooth.

Abstract: A stator for an electric motor is disclosed. The stator includes a star including a cylindrical central part around which a plurality of teeth extend radially, and a plurality of bobbins configured firstly to receive turns of a winding wire in order to form a coil, and secondly to be positioned around the respective teeth of the star. The star includes a plurality of openings formed in the central part thereof between the teeth. The bobbins include a positioning pin arranged on an inner radial part of the bobbin. When the bobbin is mounted on the star, the positioning pin is configured to be positioned in an associated opening of the star so as to position the bobbin relative to the star in the axial direction.

Abstract: A stator for an electric motor is disclosed. The stator includes a star including a plurality of radially extending teeth, and a plurality of bobbins configured firstly to receive turns of a winding wire in order to form a plurality of coils, and secondly to be positioned on the respective teeth of the star. The teeth include an end part the cross section of which is constant. The bobbins include a first end of a flared shape, a second end opposite to the first end and of a flared shape, and a central part positioned between the first end and the second end. The cross section of the central part is smaller in comparison with the cross section of the first end and the second end.

Abstract: A method for controlling a brushless and sensorless, direct current electric motor (3) for motor vehicle equipment, wherein the electric motor (3) comprises a rotor and phases (A, B, C) powered by a pulse width modulation applied to a power inverter (1) of the electric motor (3), and wherein, beyond a minimum threshold (Smin) of the rotation speed of the rotor, the position of the rotor is determined from a measurement of electromotive forces at the phases (A, B, C) of the electric motor (3), said control method is characterised in that, in the event of a command (104) to stop the electric motor (3), the speed of rotation of the rotor is reduced (105) from a nominal speed to a predetermined rotation speed (V1) within a range between the minimum threshold (Smin) and 10% above said minimum threshold (Smin) by modifying the pulse width modulation, then the electric motor (3) is stopped (106) in a predetermined position by short-circuiting the branches (A, B, C) of the inverter (1) when the predetermined position is reached.

Abstract: The subject matter of the present invention is a module (5) for cleaning an optical element protection device (3) intended to equip a motor vehicle, said protection device (3) having a surface of revolution configured to be arranged around the optical element. The cleaning module (5) includes at least one ring (51) configured to surround the protection device (3) and includes at least one wiping structure. The ring (51) is configured to be mobile in relative movement in translation along an axis of revolution (A2) of the ring (51) relative to the protection device (3) such that said at least one wiping structure (53) of the ring (51) is configured to wipe the surface of revolution of the protection device (3).
