the additional current.Tm = time in seconds from the beginning of the short-circuit to the moment when the additional cur-rent is at maximum.ti c= distance between slo^ centers.V <= surface velocity of the armature.Vx) == surface velocity of the rotary field.Vje = surface velocity of the commutator.Wr = frictional loss on the commutator.Wu = loss by transition of current under the positive andnegative brushes. ^f, = /3 -=r=i width of the commutator segments reduced to the periphery of the armature.A P = drop of voltage under the brushes.A e = maximum e.m.f. induced between the brush tips.Ap= Ae-fr= maximum potential difference between the brushtips.d = air-space. Xjf = magnetic conductivity per cm length of the slot.Xq = specific conductivity of the armature field along the periphery of the armature.T = polar pitch. Tfc = polar pitch referred to the commutator.^^ = slot field.Cos (f = power factor.y^ =3 ratio between the energy of a machine as converterand direct-current generator.
