nD

Instead of being reliant upon 2D drawings and documents, increasingly design will rely upon BIM, building information modelling (not just 3D, but also allowing time, cost and other dimensions to be assessed – so called nD).

I understand this to mean we have to assume nD-reciprocal space to make sense of quasicrystals.

The necessary n vectors span a nD-reciprocal space.

D+A = nD (D is labor division in a given economic system, A new activities of entrepreneurs and nD the resulting new form of labor division.)

A solution according to the rotor speed yields the following: snD = nD - n

Commensurately the rotor virtually accepts torque nD of the rotating field which it, however, never actually attains.

5. Asynchronous motors Hans-Friedrich Hoyer 1991

The relative difference n between both speeds, which expresses the relative movement between the stator rotating field and the rotor, is characterised as slip speed ns in asynchronous machines. slip speed ns = nrel = nD - n

5. Asynchronous motors Hans-Friedrich Hoyer 1991

For the calculation of the rotational speed of the rotating field we have nD = f/p where: nD rotational speed of the rotating field

8. Three-phase Current 1991

Rotor speed n lags behind the synchronous speed nD and one refers to rotor “slippage”.
