Rotatable drum laundry machine and control method thereof

A method for operating a washing machine comprising a casing, a laundry drum mounted inside said casing to rotate about a rotation axis, and an electric motor configured to rotate said laundry drum about said rotation axis, the method comprising:

• generating a sinusoidal motor speed profile (RS(t));
• controlling said electric motor based on said sinusoidal motor speed profile (RS);
• estimating an unbalance value indicative of an unbalance of said load in said laundry drum;
• estimating an inertia value indicative of an inertia of said load in said laundry drum,
• generating a modified sinusoidal motor speed profile by varying an amplitude of said sinusoidal speed profile based on said estimated unbalance value and said inertia value,
• controlling said electric motor based on said modified sinusoidal motor speed profile to thereby redistribute said load in said laundry drum to reduce said unbalance of said load in said laundry drum.
