<p>A system and a process for detecting a load of clothes in an automatic laundry machine, comprising a voltage sensor (30), a rotation sensor (40), and a control unit (20) which is supplied with data representative of the medium torque Mmot of the electric motor (10) in different voltage ranges and with data representative of acceleration and deceleration reference times (Ta1 and Td1) of the electric motor (10) with the basket (3) in a unloaded condition and containing a load of clothes, between two distinct and predetermined rotation values of the electric motor (10), so as to calculate the moments of inertia (Jv, Jc) of the basket (3) in the unloaded and in the loaded conditions, said control unit (20) calculating the difference between said moments of inertia (Jc e Jv) of the basket (3) and producing a signal representative of the mass of the load of clothes.</p> |
