It includes a gear set, and each planetary gear passes through a gear section of the input shaft. Planetary gears are driven by the motor unit, connecting the input shaft to the output coupling element. They are adjusted to rotate together around the same axis of rotation. The motor unit has an input shaft of 10 and torque transmission path while maintaining coaxiality at the output coupling element line. It is centered. A compact reduction is achieved with planetary gear architecture, while the axis... Eccentric loads, vibrations, and noise caused by misalignment are reduced. Ideally, the output coupling element is adjusted to be coaxial with the input shaft.

It includes a flange positioned in this way. In the structure driven by planetary gears, the flange is positioned in the planetary gears. Direct interaction with the gear reduces the need for intermediate elements, thus shortening the torque transmission chain. 5 Contact stability is achieved by distributing axial and radial loads onto the ring portion of the housing. and durability is increasing. Preferably, at least three drive units distributed circumferentially around the longitudinal axis of rotation. It contains 10 planetary gears. With the coaxial reduction structure described in the first item, At least three planetary gears working together increase torque by providing peripheral load sharing.
