  • Publication number: 20260204958
    Abstract: A two-phase brushless electric motor has a rotor and a stator, the stator including a stack of cut ferromagnetic laminations having two teeth each extending along a median radial axis, the median radial axes being coplanar. The cross-section of the stator is inscribed within a rectangle having a length L1 and a width L2. Each of the teeth is surrounded by an electrical coil. The rotor comprises three, four or five pairs of magnetic poles, which are radially magnetized in alternating directions. The median radial axes form an angular sector therebetween that extends over an angle of between 145° and 180° and the stator has at least one mechanical and magnetic continuity extending between the two wound teeth.

  • Publication number: 20230198337
    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.

  • Patent number: 10756602
    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.
