speed for example on reaching 80 90 r p m ie a speed less than the orbital speed which in the present example is 120 r p m point y of fig3 the signal relative to the speed sensor or current sensor reaching the electronic module indicates that these fluctuations have been substantially reduced to an acceptable predetermined level point x of fig3 and that at that moment the load is distributed in a substantially balanced manner over the wall of the drum 4 a possible explanation of this phenomenon is that at this speed for example 80 90 r p m the load has only partially orbited in that this speed is insufficiently high to overcome the force of gravity to which the clothes in the central part of the drum are subjected and which are only dragged by the rotation of the drum itself these clothes dragged into rotation are however subjected to a centrifugal force which at certain moments for example because by rolling those clothes not in orbit become positioned in a region of the drum to which a smaller quantity of clothes adheres hence in a region in which having a greater possibility of radial movement they are subjected to a greater centrifugal force can overall determine the balanced load condition on sensing this state of equilibrium the electronic module 14 passes this information to the timer 15 which conversely causes the electronic module 14 to feed maximum power to the motor 10 which undergoes the highest acceleration sections p and q of fig3 provided for spinning so orbiting.
