Abstract (en)
[origin: EP1447469A2] The method determines the mass inertia moment of the loaded laundry drum from the measured electrical power requirements (P1,P2) of the electric drive motor for rotation of the laundry drum at 2 different constant rev values (n1,n2) and during an acceleration phase for increasing the revs from the lower constant revs to the higher constant revs, the measured power requirements inserted in a defined equation.
