Abstract
In a spin extractor, an eccentric load judging unit judges the magnitude of the eccentric load based on the amplitude of fluctuations in the motor current while a drum is rotated at a speed at which the centrifugal force on fabric articles contained in the drum is a little larger than the gravity. If the magnitude of the eccentric load detected is larger than predetermined, a balance correcting operation is conducted by a speed control unit. That is, a speed reducing position designating unit sends a pulse signal to the speed control unit at the moment when the eccentric load of the drum comes just before the highest position, in response to which the speed of the drum is reduced momentarily. When the speed is reduced, the centrifugal force is smaller than the gravity, so that the fabric articles crammed and piled fall off the inner peripheral wall of the drum. Thus the fabric articles can be scattered almost evenly.
