Abstract: A gear motor comprising a reduction gear train and a three-phase electric motor comprising a stator formed of a stack of sheets and 3*k electric coils and a rotor having 5 k*N pairs of magnetized poles, with k=1 or 2, the stator having two separate angular sectors alpha 1 and alpha 2, which are centered on the center of rotation of the motor and comprise an alternation of notches and 3*k*N teeth, which are regularly spaced and converge toward the center of rotation and define a cavity in which the rotor is arranged, the gear motor being characterized in that N=4 and in that alpha 1 is less than or equal to 180° and comprises all of the coils of the motor.

Abstract: An electric motor includes a cylindrical wound stator assembly forming a free interior space and a rotor assembly guided inside the interior space. The reduction gear is inside a housing secured to the stator assembly and having a movable gearing assembly. The output of the movable gearing assembly is secured to a movement output shaft. The input element of the movable gearing is driven by the rotor assembly extending inside the housing. The gear motor comprises a guide element of the output shaft. The output shaft is extended inside the motor up to a guide element located at least partly inside the stator assembly having the rotor assembly which is guided by a guide means positioned between the inner surface of the rotor assembly and a surface of the output shaft.

Abstract: An electric machine comprising a first and a second three-phase winding and comprising a stator formed of a cylindrical yoke made of a soft ferromagnetic material extended radially by a set of teeth, a portion of the set of teeth bearing the windings, the windings being distinct from one another, the first three-phase winding being connected in a delta configuration, the second three-phase winding being connected in a star configuration.

Abstract: The disclosure presents a geared motor unit including a housing having an electric motor formed of a coiled stator assembly and of a magnetized rotor, the housing further including a printed circuit board for connecting and controlling the motor, a movement-reducing gear train, a sensor magnet and a magnetosensitive probe. The gear train includes a toothed movement output gear, the sensor magnet being ring-shaped and being rigidly connected to the output gear. An output gear is extended on either side of the sensor magnet by two guides cooperating with the two opposite walls of the housing; a ring-shaped magnet surrounds the axis of rotation of the output gear; a printed circuit board includes a controller controlling the motor and extends up to the vicinity of the output gear.
