Abstract: The present invention relates to a method for controlling a laundry treatment machine (1) comprising an outer casing (2), a washing group which is placed inside the outer casing (2) and comprises, in turn, a rotatable drum (6) structured for housing the laundry to be treated, an electric motor (16) for rotating the drum (6); the method comprises the steps of: controlling the electric motor (16) to cause the drum (6) to change its rotational speed according to a prefixed reference speed profile comprising at least an acceleration ramp (Ra(i)), wherein the drum (6) is accelerated from a low speed (B1) to a prefixed high speed (B2) and at least a constant speed phase (S(k)) wherein the drum speed is maintained about the high speed (B2), sampling first torque values (Ti) generated by the electric motor (16) during the acceleration ramp (Ra(i)) according to a prefixed first sample time (Δta), sampling second torque values (Tj) generated by the electric motor (16) during the constant speed phase (S(k)) according to a prefixed second sample time (Δtb), calculating a third value (TU), which is indicative of an average torque value based on said second torque values (Tj), determining a fourth value by performing an approximate integral calculus consisting of subtracting said third value (TU) from said first torque values (Ti), and determining the amount of laundry load (QL) on the basis of said fourth torque value (Torque_int).

Abstract: The invention relates to a washing machine (1) having a first single phase electric motor (M1), a second single phase electric motor (M2) and an electric drive unit (100; 100') for the electric motors (M1, M2). The electric drive unit (100; 100') is connected to power supply lines (PS1, PS2) and comprises three first legs (L1, L2, L3), each leg comprising a couple of switches. Electrical terminals (M1a, M1b) of the first electric motor (M1) are connected to the first and second legs (L1, L2) of the electric drive unit (100; 100') and electrical terminals (M2a, M2b) of the second electric motor (M2) are connected to the second and third legs (L1, L2) of the electric drive unit (100;100').
