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.

A magnet gear device includes a first magnet unit in which two or more magnetic poles are alternately arranged in a direction along a rotation axis and a circumferential direction with respect to the rotation axis, respectively; a second magnet unit in which two or more magnetic poles are alternately arranged in the direction along the rotation axis and the circumferential direction, respectively, wherein the second magnet unit is disposed radially outside the first magnet unit; and a pole piece unit including a plurality of pole pieces to form a magnetic flux path between the first magnet unit and the second magnet unit. Each of the plurality of pole pieces is formed to extend in a radial direction to allow each of both an inner end and an outer end thereof to overlap at least a portion of the first magnet unit and the second magnet unit.

Disclosed is a sensing device comprising: a stator connected to a first shaft; a first gear rotating in engagement with the stator; a second gear rotating in engagement with the first gear; a magnet coupled to the second gear; and a magnetic element disposed corresponding to the magnet, wherein one surface of the magnet disposed facing the magnetic element has an elliptical shape. Accordingly, even when the center of the magnet disposed in the second gear and the center of the magnetic element are not aligned in the axial direction and thus arranged offset, the sensing device can enhance the precision of a steering angle measurement due to the shape of the magnet.

A planetary gearbox with two rows of planets, at least some of the planets including magnets. The planets are driven by a stator to drive the gearbox as a motor. The planets may be geared with axial portions with different helix angle to position the gears and avoid the need for a planet carrier or bearings. Gears with small heights and/or high pressure angles may be used to avoiding or reduce negative effects of conventional gearing.
