Drive unit

A motor, comprising:

• a housing;
• a first stator lodged inside the housing;
• a first rotor inserted in the housing inside the first stator and comprising a first rotor shaft rotatable around a rotation axis and a first sun gear coupled to the first rotor shaft;
• a first planetary gear set placed inside the housing, comprising a first ring gear fixed to the housing, a plurality of first planet gears in meshing engagement between the first sun gear and the first ring gear, and a first planet carrier supporting the plurality of first planet gears, the first planet carrier comprising an axial protrusion developing along the rotation axis and defining a first gear shaft concentric to the first rotor shaft;
• a first support bearing interposed between the first rotor shaft and the first gear shaft, and a first support blocking element applied to the first support bearing and configured to prevent axial movement of the first support bearing;
• a second stator lodged inside the housing;
• a second rotor inserted in the housing inside the second stator and comprising a second rotor shaft rotatable around a rotation axis and a second sun gear coupled to the second rotor shaft;
• a second planetary gear set placed inside the housing, comprising a second ring gear fixed to the housing, a plurality of second planet gears in meshing engagement between the second sun gear and the second ring gear, and a second planet carrier supporting the plurality of second planet gears, the second planet carrier comprising an axial protrusion developing along the rotation axis and defining a second gear shaft concentric to the second rotor shaft;
• and
• a second support bearing interposed between the second rotor shaft and the second gear shaft, and a second support blocking element applied to the second support bearing and configured to prevent axial movement of the second support bearing;
• wherein the first gear shaft is coaxial with the second gear shaft and faced outward in opposite directions.
