A system and a process for detecting a load of clothes in an automatic laundry machine, comprising a voltage sensor, a rotation sensor, and a control unit associated with a timer, with the voltage sensor, and with the rotation sensor and which is supplied with data representative of the medium torque Mmot of the electric motor in different voltage ranges and with data representative of the acceleration and deceleration reference times (Ta 1 and Td 1 ) of the electric motor with the basket in the unloaded condition and containing a load of clothes, between two distinct and predetermined rotation values of the electric motor, so as to calculate the moments of inertia (Jv, Jc) of the basket in the unloaded and in the loaded conditions, said control unit calculating the difference between said moments of inertia (Jc e Jv) of the basket and producing a signal representative of the mass of the load of clothes.
