<p>Household-type clothes washing machine comprising a rotating drum for holding the clothes to be washed and/or dried, adapted to rotate about a substantially- horizontal axis; a universal motor (1) adapted to rotatably drive said drum,- means for controlling the motor current; means for measuring a quantity that is representative of the driving torque supplied by said motor, said measurement means comprising at least an additional coil (5) adapted to link up with the electromagnetic flux passing through said motor. Said machine is provided with means for processing the electric signal produced by said additional coil so as to be adapted to deliver the driving torque of said motor. Preferably, said signal processing means comprise an integrator circuit and a circuit for detecting the peak-to-peak voltage connected in a series arrangement to each other.</p> |
