Abstract
The disclosure relates to a motoreducer consisting of a casing including a brushless motor having at least two electrical phases, a rotor rotating on an axle, and composed of a stator assembly having at least two poles each bearing coils the winding axes of which are spaced apart by a mechanical angle smaller than 180° and extend radially, and a gear train. The gear train includes: a first axle placed in the angular space formed between the two poles, the first axle bearing a first assembly formed by a coupled pinion and toothed wheel, the toothed wheel being placed above the pinion and having a radius larger than the pinion, the toothed wheel meshing with an input pinion rotating on the axle of the rotor, the toothed wheel being placed above the poles bearing the coils, all the axles of the gear train being parallel to one another and parallel to the axle of the rotor. The gear train has at least one axle bearing two toothed wheels/pinion assemblies rotating on the axle.
