A method for redistributing a laundry load in a drum of a washing machine in order to reduce the unbalance generated to the nonuniform distribution of said laundry load in said drum. The method comprises: generating a sinusoidal motor speed profile (RS(t)), controlling the electric motor based on the sinusoidal motor speed profile (RS(t)), estimating unbalance value indicative of the unbalance of load in the laundry drum, estimating an inertia value indicative of the inertia of the load in the laundry drum, varying the amplitude of the sinusoidal speed profile (RS(t)) based on estimated unbalance value and inertia value, and controlling said electric motor based on modified sinusoidal motor speed profile.
