The following constant values are defined, : [[tau].sub.e] = [L.sub.a]/[R.sub.a] - time electromagnetic constant
, ; [[tau].sub.m] = [R.sub.a] J/[k.sup.2] - time electromechanical constant of the electric drive system.
where [F.sub.0]--the braking force of the ideal motor without the edge effects; [h.sub.s] -the coefficient evaluating the transversal edge effect; [[epsilon].sub.0]--magnetic number of Reynolds, [T.sub.e]--an electromagnetic constant
of time; [K.sub.c] and [K.sub.s]--integral functions dependent to the Fresnel's integrals.
Replacing the dimensions and introducing new electromagnetic constants
is a purely technical problem, although it is hardly practicable today.
