Abstract
A method of sensing the motion of the wash assembly () of a washing machine () due to the dynamic unbalance of the laundry drum assembly (), and which comprises the steps of: increasing the rotation speed (ω) of a laundry drum () to a first rotation speed (ω); determining a first parameter (T; A) related to the time pattern of the values of an unbalance function A=T−Jdω/dt; increasing the rotation speed (ω) of the laundry drum () by a predetermined value (Δω) determining, at each increase (Δω) in rotation speed (ω), a second parameter (A; A) related to the time pattern of the values of the unbalance function A=T−Jdω/dt filtered at the predetermined filtration frequency (LF; HF); calculating the difference (T; T) between the second parameter (A; A) and the first parameter (T; A).
