<p>A means for quickly stopping the rotation of the motor (1), and thus of the drum, of a washing machine or a combined washer and dryer for laundry, after the spinning phases provided during washing. The means comprises a relay (5) equipped with an electromagnet (6) connected, in series with the programmer-retarder (4) of the machine, between the electric main (7) and the neutral conductor (9), said electromagnet being adapted to move into two different positions a moving contact (10) connected to the stator and rotor windings (2, 3) of the motor (1), thereby supplying or interrupting the supply of power to the motor. In the latter case, the motor (1) is thus driven by the inertial movement of the drum that generates an electric current so as to produce a braking action that quickly stops the motor (1) and the drum. Advantages: the total duration of the washing programs is considerably reduced, resulting in lower power consumption by the machine.</p> |
