ABSTRACT:
A detecting device of unbalance conditions, particularly for washing machines (1) and similar household appliances comprising a rotary drum (2a) supported by a tank (2) and activated by a synchronous electric motor (3) with an internal stator (5) having corresponding windings fixedly mounted on a central axis (10). The detecting device comprises an electronic control board (18) for the synchronous motor (3) associated with the stator (5) and incorporating at least one accelerometer (51) to constantly monitor the acceleration of said tank (2) and indirectly the unbalance of said washing machine (1) and the unbalance of a load comprised in the rotary drum (2a).
