In a weight motor, it is known that friction can be among the most difficult elements to successfully accommodate. In this invention, three pinion gears are assembled to engage one another in-train and are further engaged by a cog wheel which surrounds them all, such that the sum of the pitch diameters of the three pinion gears equals the pitch diameter of the internally geared cog wheel. While the axles of the central pinion gear and one of the adjacent pinion wheels are seated in fixed bearings or journal boxes, the axle of the third pinion is un-anchored and unimpeded from rising or falling. However, because it must influence the activity of the other three gears (including the cog wheel) which together hold it in its place, its ability to achieve rest/stasis at the "bottom" of the system can never be accomplished. Its own weight, or similar pressure against it, must cause it perpetually to seek a final rest point, yet never to reach it. A further pinion gear assembly may be constructed to impinge against the outer diameter of the cog wheel (where that cog wheel has had gear teeth cut into the outer diameter of it as well as into the inner diameter of it) and in line with the line/train described by the inner three pinion wheels. Such a train of gears is at right angles to the direction of gravity, or to the direction of a chosen alternative activating force. In most favoured design cases, gear assemblies are used "in-mirror", such that each assembly has a similar configuration/assembly of gears and related elements on the opposite (lateral, but virtually the same planel) side of the motor, and the proximal gears of such mirrored assemblies share two axles in-common.
