  We report a measurement of the inclusive electron energy spectrum for charmed
semileptonic decays of B mesons in a 140 fb^-1 data sample collected on the
Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric energy
e^+ e^- collider. We determine the first, second and third moments of the
electron energy spectrum for threshold values of the electron energy between
0.4 and 1.5 GeV.
